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




Attached thumbnail(s)

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
