but already install Philip one with casing ...

so other might go for China T8 22w ....

thanks ....

Please keep in mind when selecting LED Tube on these criteria
1. Power Factor
PHILIPS EcoFit has low PF compared to their other range such as InstaFit. I can’t recall as I have left PHILIPS in 2016.
2. CRI (Color Rendering Index)
This will give you a better rendering of color if it’s 70 and above
3. THD (Total harmonic Distortion)
For home usage, I will skip this part

Good to know that there are so much choices in the market. In fact, PHILIPS LEDtube are ODM by Aztech and other manufacturers. Even GE is OEM by FSL if I’m not mistaken.

Cons: magnetic ballast consume 6-8 watt in additional to led tube wattage. I am not sure if the life of the tube is shorter using this method but the function of ballast is only limiting the current flow. LED need less current than normal tube

Correction - ballast will not run at 6-8watt but instead contribute 1w as the current draw from the LEDTube is lower. Hence the resistance on the ballast is lower.

Secondly as the ballast act as step down transformer, there is no impact on the LEDTube lifetime. Unless the ballast is pretty worn out and need to be replaced. After all nowadays magnetic ballast (even tho low loss) the material used are inferior compared to last time.

With the ballast, it also act as a layer of defence against surge.

for the T8 casing, do you utilize all 3 wires including Earth? since LED normally only have Live & neutral. do you connect the earth to some screws on the metal casing?
*
Yes. Earthing to the casing as standard practise.
This is to obtain class 1

can i use a wire connector and insert it between the bracket & screw (into plug), or will i risk damaging the connector if i screwed the screw in too tight to the ceiling?
*
Sorry. I think I lost you here.
The purpose to connect the Earth wire to the chassis is to act as protection if there’s leakage from AC (Live/Neutral) which will trip the circuit breaker

the support bracket is normally metal, once you install the bracket then you can screw the light casing onto the bracket. so if i use those wire connector (donut) and slip it between the screw & casing it will work right? because that is the only place which have screw to secure the ground.
*
Yeah. As long as the wire is connected to the chassis

6W loss for 18W current draw for a typical magnetic ballast.
*
Yes, for 36W Fluorescent tube.
If LED, it's lower... try use the power logger

Sorry, i gone through my file. I didn't save the power logging file with retrofit ballast.
However, I can assure you the loss is minimal about 1w

how many w for your t8 tube ?
Philips or China T8?
any way to improve em insulation for LED panel driver ?

Philip T8 solve the noise ...but room LED panel light turn on the noise come back again ...

thanks ....

Replace with diff driver? Coz the driver usually the culprit.
You need to invest in a good driver with low EM, high PF

how to know good driver ? anyway to check b4 purchase?
usually cost rm15 below for 18w ...

thanks ..

Usually it’s the product specs on wattage, power factor , liken output, lifetime and CRI.
EM rating usually not shared unless you requested for test report

hi just wanted to ask..

what's the difference between this two?
https://www.lazada.com.my/products/10pcs-ph...s143539336.html

and this

https://www.lazada.com.my/products/10-pcs-p...s109242009.html

in terms of energy saving, quality of light and compatible with current casing?
*
Image shown can be misleading.

However,
https://www.lazada.com.my/products/10pcs-ph...s143539336.html

It said come with bypass starter. so u just need to just direct replace existing fitting

glass type or plastic casing ?
Pls refer attached driver photo ...anyway to know less distortion driver ?
one come with by pass starter...meaning to say just remove your current starter and insert Philips starter ..the Philip led light will turn on without remove the ballast....

another one without the starter...need rewiring the wire according Philips LED tube wiring ...

thanks ...

Hard to see from the image alone.
If got brochure,maybe easier.

What if the ballast failed after using Phillips led tube for a while? Need to replace with traditional ballast again?

Just bypass the ballast. Meaning do rewiring

Then might as well do wiring straight away and make do without bypass starter

Can also. Up to u. By bypassing the ballast u get additional saving. Roughly 1w.

Durable yes but probably not until 20 years for my case. If not faulty, it might be noisy

Try first. Magnetic ballast won’t spoilt easily. They just step down the voltage.

thank you. I can't find 20w in Lazada and I also can't find any electrical supply shop in Bangi or Kajang or Dengkil who sold this 😅😅😅

Try contact KVC Industrial supplies in Bangi

Any advantages of Philips LED Linea Batten Slimline over Ecofit LEDtube?
Linea Batten

Linea is an integrated batten. The beauty is it’s slim and nice looking fitting.

The drawback is getting back same replacement in near future
