My experience is that most led lights failure is due to the driver.

The drivers provided looks cheap and flimsy.

I have a couple of laptop adaptors lying around.

Can i use them to replace the led drivers?

Attached photo for reference. Can i replace the one on the left with the one on the right?

You need a 24VDC output.

That laptop adaptor is only 19VDC output.

I m using Laptop adaptor to power my LED also. 4yrs and still lighting now.

tq for your reply. So your laptop adaptor is 24v dc?

Good DC switching power supply cost around RM 50 onwards. Depending on wattage and protection circuit inside. Here one example

https://www.lelong.com.my/meanwell-lrs-50-5...7-01-Sale-I.htm

Nope. It is 16vdc. Cause the led require 17vdc only.

Actually another sign of cheap led is the led itself. The cheap ones will tend to yellow or blur out and making light dimmer. This is because the manufacturer over drive it (like cpu over clock it)

Pretty normal for China led.

They use the most easy way to scam. The cheap price.

The branded lighting company like osram, philip, ge Bright LED light are not cheap, but many consumer they just want cheap and look nice. Reliability is secondary.

What are good reliable LED drivers used or known so far?

So basically in my case if the led light requires less than 19v then i can use the laptop adaptor ya?

Your original driver are constant current, variable voltage, is different from and standard DC adapter or notebook. even if you can run at 19v, your led will be dimmer.

Correction, if you use notebook adapter, you risk frying your led because your led depending on constant current adapter, not voltage.

I woudnt say its a scam lah.. U pay for what u get.. But so far after 2 yrs of using those cheap ones.. The led light itself is ok.. Just the driver rosak.

Nowaday, I don't see the price gap is big.

That small amount of different can payback in a short time.

People just like to be scam by a bad product for the sick of cheap.

Compare the spec and match with the required driver from online store. Here is one you can compare

http://my.element14.com/c/lighting-product...t-current=350ma

Tq for your reply. Is LEDEON or NSB brand ok?

Thanks for this resource. How does a consumer decide how a LED driver is replaced besides matching light wattage requirement, constant current and voltage range? What else should we look for?

The main problem for the driver is the heat. Where there is no airflow and confine space hide behind the ceiling.

Heat and water is the electronic enemy.

So there is no exactly reliable driver if it place in such place.

It come to which want will run longer. Than you have to look for the quality driver brand.

I never try China driver before. Only experience with japan driver mostly. Like Omron, Minebea and TDK. This driver can last like over 10yrs without problem. But not in a confine place.

Example my this omron driver. 15yrs old. Still running. But nowaday, hardly can find it made in japan. All come from China. Only certain expensive model is still made in japan.

No. You have to match the voltage of the LED. A +- 1V is still acceptable. But too much different will not light up the LED. Or very dim.

Another problem is, it will burn down your driver. Cause lower voltage will increase the Amp.

In my case, 1V lower is still ok. Than The laptop driver can provide 16x of the LED Amp require. Actually I m wasting away the driver.

Yup. For normal people see, just as what you said, you pay what you get.

For us which understand the technical and behind the product, it called scam.

Sorry, I really don't no such brand.

Anyway, just get back the wan you brought. Since it can last 2yrs, should be good for you? (if you have difficult to get a good wan)

For the moment, I thought with LED, waste heat generated is much less. But it seems like back to square one. With CFL ballast, halogen or led driver be it modular or built in there's still heat.

I wonder if home owners who have downlights also ventilate the ceiling space be expelling the heat outside with a ceiling extractor fan or a wall mounted extractor fan to deal with this.

Put another way, where can a good led driver be sourced from?

I won't suggest to buy back the same mA. The LED might use more mA now compare to new. So get a 2x or 3x the A.

The driver can last longer.

But this is also bad for the LED. When it consume higher Amp, it produce more heat. Finally burn down the LED.

So the good way is to find a current control driver.

Dilemma.

Adding some equipment just to cool down the ceiling is ok. But just for the driver and light, will add up your light cost. Cause you change to LED is to reduce the cost.

But what about the ontop plaster ceiling and the downstair 2 storey house ? Where you can put the exhaust fan in the plaster ceiling ?

LED do generate heat. You can touch it behind the LED. It is false that LED no heat.

What different between LED, CFL, Halogen is the energy consume. But that too subject to Lumens/watt.

People told you this LED is only using 10w compare CFL using 18W. But they don't tell you the brightness of lumens/watt. If this math present, the lumens of the LED is same watt or more than the CFL.

But technology LED now improve alot lumens/watt. They are getting better. Provided you using the good LED.

Nowadays quite some numbers of LED products or salesman use wattage to misled people, and without mentioning the LED lumen.
Ended up people buying the same wattage for the LED as compare to previous CFL light.
Ended up no energy savings, and complain about LED too bright.

Only from the electronic shop or online. With some technical knowledge.

In short- not easy.

Already give you the brand. Try those brand.

Or like me, if you know your LED voltage and watt, get those old laptop adaptor or 2nd also can. This adaptor have brand like IBM etc have a better quality. Modify it and use it on the LED.

True.

I don't buy LED that doesn't tell the lumens. Crap product.

Don't buy any LED that 6500k or over. It bad for your eye when you get older. A gentle color for your eye is 3500k -5000k.

No one will know except the person design the led light. Hence is better refer the original adapter or the specification of the led light (if any)

Constant Current need to use constant current adapter, cannot run led in parallels. I have not try Supply higher current to a constant current LED circuit, maybe TS can try if it fried, a good time to buy another light.

Hi tq for reply.

Ya so far the light is ok. Did not get dim after 2.5 years. But driver has been replaced for about 10 out of about 25 lights in those 2 years. Covered under warranty though. That's why thought of using laptop adaptor to replace the driver when one goes dead again. The shop that sold me the lights sell drivers at RM20 which i think is expensive since light + driver only RM30.

Buying a new house at the moment and thinking of installing led downlights and surveying which brand is better. I believe NSB and LEDEON is cheaper than the current one i am using which is a electricial distributors in house brand.

If any of you have used NSB or LEDEON please do feedback. TQ.

tumpang tanya


one of my milo can lights fused already. i took it apart, no driver inside.
it runs on 230VAC
where to buy replacement? I never seen this before anywhere

what is that round thing ?

The 1st pic? That's the led module
Cannot open up further. Must change the whole module
You see those whitish stuff on the edges ? Looks like heat sink compound to dissipate heat

The driver is built inside the LED in this case.

That white thing is heat dissipate compound.

No choice. You got to buy that round thing whole pcs. If they have such spare part selling.

Probably you have to buy the whole LED light.

Suggest : If the price too expensive, modify it to use LED bulb. Buy the E27 socket and screw to the milo tin. Get a 1000> lumens LED bulb. Work the same and future proof.

Outside is make in malaysia, inside is made in china. Sound more logic if its made in china, assembly in Malaysia.

LED with build in driver lifespan are short, even shorter if its bright LED.

How you hang this milo tin ?

I don't see any bracket at the back of the 2nd pic?

Just buy a good one with reputable brand like Philips. Save the hassle changing the driver. It will save a lot in the long run although initial cost will slight higher. My LED bulbs or spotlights had not been replaced since 3 years ago.

I quite don't why people keep buying the cheap LED with low quality driver. As they already knew they need to change it within 2 years.

I got a spare one and already replaced but next time when fused, I will buy a different light.
Too much trouble to go look for this spare which I think only philips sells

Yes, I think the led itself is imported from china then the milo casing made here
No driver accessible next time will just replace with a different light fixture. Common one

After take photos for you to see

LED is trendy, save electric maybe, ROI i doubt due to short life of driver or the light itself.

Is still not as reliable as CFL light. Only the low power LED are reliable, not the Bright LED. ROI better don't think about it.

Philips lighting

I bought the smart led downlight (about 25 pieces - 3 with controller, 22 without) in 2016 with an additional 10 or 15% discount. I am personally very happy with it. There's 3 colors - 3k, 4k and 6k i think and 3 brightness levels. Very convenient. Drivers are built in.

So far, only 1 gave problems where it died after few days, replacement unit provided in 2 days. The others are still working fine until today.

the philips normal ones arent much more expensive compared to china brands, so i would get the philips ones anytime.

edit: the downlights are rated at only 600 lumens but its extremely bright, comparable to 1k+ lumens china brand

forgot about the pics, just remembered....hehe...




Attached thumbnail(s)

oh, so it have another adaptor twist and lock.

yup....

Buy the lowest powered rated LED bulb with the highest lumen say a bunch of 5W using the same physical profile as a 12W

The passive electronic components will most likely last the rated 50k hours..

The reliablility you mention is directly proportional to how hard it is being driven..

LED is just a diode.. overloaded.. it burns..

So don't..

for reading ...3500k ~ 5000k enough bright ?

still can share the link ?

my 18w panel LED light driver slowly down after 4years plus using ....now finding good driver ...


thanks ....

That is color of the light. Not brightness.

Kelvin k - light color. Ex,2900k, 3500k, 5000k, 6500k
Lumens Lm - brightness. Ex, 600lm, 1200lm, 1600lm

5000k ..一the colour will be yellowish?

Nope. Toward to white. But not too white (6500k).

Hey, can help me out pls?

My current driver is: input ac85-265v 50/60hz, output 270ma.

The new driver is similar spec as above, but it is only 240-260ma.

Can the new driver work on my led? It's 12w downlight.

It is enough.

12w with efficiency of 80%, it use 60mA.

Ok thanks.

how is the formula calculation?
my surface mount LED was 18w
the photo driver spoiled ..how to choice replacement for my LED driver?


thanks ...


Attached thumbnail(s)

I cincai calculate only. Since his replacement A in not much different (only 10ma), that should be ok.

But for your case, you need to tell me the LED running DC voltage.

The driver DC range is DC38-68V cannot know exactly what is the led voltage.

If I use DC38v than 18w/18v=470ma. That is over the driver spec.

If I use DC68w than 18w/68v=260ma. That is still over the driver spec when included the efficiency of 80% = 325ma.

If really the led run on DC38v, 18/38=470/80%=600ma. You need to get a driver 800ma or over.



But but but but but........why original driver is under spec ? (300ma)

It is another way of control the LED lifetime. But the driver spec doesn't tell anything about it to control the LED lifetime.

Wah Ozak you seem like a pro. How about brands like this? Philips. Its 10watts and 6500k but didnt mention whether it is how many lumens. Need about 30 units of this. 4 for each hall and rooms. You think its bright enough? Can last long? Cause nowadays they said no longer use the buld and reflector type already.

https://www.lazada.com.my/products/12pcs-x-...0927f678214b34d

how to know my surface mount LED running how many DC voltage? calculate how many pcs of the LED?

thanks ...

Not written on the led light?

Sorry bro, not pro. I bullshit alot here.

I never use Philip before. But did mention the lumens is 900lm. Quality not sure.

I don't know bright enough for your room or not. Cause got to consider the room size, height and equal distribution. 6500k have a bad on this big room size. If it not bright enough, create a ghost atmosphere.

It is bullshit that no longer use bulb and reflector type. Led bulb are now selling everywhere.

If for me to play safe, I will use Led bulb and reflector. If not bright enough, I can change the bulb.

As slimey said, the casing should have some spec wrote on it.

If don't have, need a multimeter to check from the driver wire to the led.

Hi there, it is about 900 lumens. This light is quite bright and has a high efficacy (lm/W). The newer Philips downlights are 17W and have slightly higher lumen only, which means a lower efficacy.

I use 2 of these for a small bedroom, and 2 for my porch. Very bright and uniform light throw, definitely much better than the China lights.

nope...just small small LEDs round around the casing..

no have ...
multimeter set to measure voltage DC output from the driver?

Yes.

Driver wire to Led only have 2 wire. Each probe to 1 wire. Or probe on the connector at the led side. Meter set to DC.

Without the lumens number, it is hard to tell the brightness. Very subjective.

I said that lenglui is pretty. But you said like auntie. How ?

I said the color is red. But you see it is pink. How ?

You said bright, my imagination is like sun. Too bright. How ?

By lumens you mean the Philips 59203 lumens? I did mention it is at 900.

From my experience, those China lights typically at 18W is rated at 9xx lumens. For those such as Philips or LEDvance (Osram), they're good for 900~950 lumens at 10W. That's an improved efficiency or efficacy by quite a margin.

More than that, the light throw also matters. The diffuser of the China branded lights actually causes a high loss of light diffused through versus better diffuser designs of those branded lights.

Use a lux meter to measure the light at a few areas around your room after installation, the simplest lux meter you can find is your phone. Install a China branded light and measure it, then repeat the same with a better light. From there you can tell which light has a better light distribution and light throw. There are guides to comfortable lux levels for different settings, typically ranging from 100~200 for homes. Just looking at the lumens written on the box can sometimes be misleading.

Lumens = measure of light output
Lux = measure of lumens/area

There are some chinese branded lights that are really bright, but the trade-off is a low lifespan, or the brightness decreases lower than the 70% threshold when new very quickly. But from experience, just by installing and comparing one can tell the difference.

There are also chinese-branded lights that are equivalent or on par with the European brands such as Opple, FSL (but at a premium over regular chinese-branded lights). Even the European brands manufacture their lights in China.

Hi all
I can’t seem to find a comparable spec to my driver. Any recommendations? 1 year can blow 6 times. But managed to reduce to about 1x after wrapping this with plastic for use on toilet ceiling

Guys WTA,

Sorry sidetrack and tumpang thread abit, since talking abt Led drivers , anyone here using these Philips Led lights, thinking of replacing most of my downlights to these, my current China made ones seem to last on average a year at most, its mostly the drivers giving problems.

Thanks

This post has been edited by cablesguy: Jun 13 2020, 09:24 PM

how many w for your light ?
the driver support from 13w~18w

18W. Not sure why 1 year can blow a few.
Decided to try to order from China. Hopefully gives longer life at cheaper price.

https://m.intl.taobao.com/detail/detail.htm...42.608245840791

no need order from taobao order from shopee can already ..

Your toilet given up a lot of moisture that cause the driver condense of water. This might be the reason cause the driver spoil.

You might consider getting another LED light that is seal off the driver. (Enclose together with the driver inside and seal off. It have somekind of alloy heatsink at behind.

Or place away from the driver away from the top center ceiling.

Or bath less hot water. Where the hot steam create this problem.

I saw those at Shopee. The PCB is smaller and looked cramped. So I bought the full size one from China.

About Rm8 each driver prorated including delivery for 5units. Only thing is I need to desolder and change the cable to NSB’s connector (or otherwise use a generic connector through the cable)

after received post photo here for the driver look ...

thanks..

Sure. will share when i received it.

Also does anyone know what drives the color of LED, the 6000 or 4000?
Was it the driver or the LED?

Anyone know where to find a driver as such for 24watt surface LED.
