That's the shop in Kuchai Lama that I was referring to in one of my earlier post. Comparing your China 18w T8 tube, this Philips 20w will be brighter but don't expect a lot, roughly 20 -30% but still better and close to normal fluorescent tube.

I doubt with your current wiring setup, the Philips LED tube will light up as both Live & Neutral need on 1 side of the holder but your current wiring is L&N on each side separately. Alternatively, you could go for a local brand of T8 LED with 22w of 2000 lumens. Price is much less than Philips and quality close to it.

aiya...
already placed order from the lazada link that provided by you ..
haha...
hope wont damage during delivery ....

can teach how to connect the wiring from my current China T8 LED to Philip T8 LED ...appreciate ...

To modify, one side of the holder need to have both wires coming out and connect to 'L' and "N' from your electrical source and the other holder side leave it as dummy (wire not connected) .

If your holder only have 1 wire coming out and another wire no where to be seen, you may need to buy 1 holder with both wiring coming out from lighting / electrical shop which is usually very cheap.

Yes, Philips Led is Type B, LN is at one side. The seller usually will make sure the casing wiring is correct with the Philips T8 Led when both items brought together, so don't worry much.

T5 is slim version of T8 for Led. T5 comes with bracket 'LN' is at 1 side only as the main pupose of using T5 is to join the light side by side for kitchen cabinet /plaster ceiling cove lighting. Most if not all T5 led comes together with integrated bracket. The tube cannot be detached once its not functioning. Please check the T5 led at shop to understand better and the variety of lenghts available.Yes, T5 led is available in various lenghts.
Btw, this discussion is on T8.

oh no wonder so T5 all came with the LED & casing just like downlight? the whole tube just screw onto the surface you are mounting not into any casing like T8? when you say integrated means i can connect 2 T5 without additional wires just plug in? might be good for cabinets.

i was looking into T8 actually, those that when replace just pull out the tubes. are there T8 casing that supports both Fluorescent & LED without mods? is there any quality brands for T8 LED casing? T8 LED don't need Driver like Downlight do right? or Driver is in the casing?

that tube purchased about 2years ago ...price about rm5x ..

after changed to Philip tube ...is more more bright compare old tube ...
the old tube top covered by heatsink..so the light transmit covered too ...
but ..the Philip one 360' light transmit..so more bright...

China glass T8 22w 2000lm price about rm16~rm18 per tube ..

22w VS 20w ...2w different ...Electrical bill will different a lot?

China T8 -> China T8 ..just plug n light up..
China T8 -> Philip T8 .. need re wiring ...

thanks ...

All T8 Led driver is embeeded inside the tube, i.e no external driver needed. Thats the advantage of using T8 led.

2w is minimal. The price of 22w China/local 2000lm is much lower if you get it from main dealer. It does not make sense if it is same price as 20w Philips with but less 100lm.

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?
