Did you manage to find t4 lights? I just bought a floor lamp which I thought was t5 but ended up being a t4!!! :'( and have scouref kl selangor withouy any luck.

phoenixxx nope, have to buy a T5 to replace

LED or common energy saving bulbs are more efficient and practical?

for the whole house, or should i mix ?

guys please advise...

LED is the most energy efficient, but the initial cost to bought it is quite high. Energy saving bulbs are also energy efficient but not as efficient as LED, but its initial cost is cheap. Why dont you include T5 bulb in your listing?

thank you, i havent had much luck too, should'nt have trusted the guy when he told me it was T5 (i didnt know any better actually). anyhow probably can chuck the lamp away or mod it with some LED strips in the future...

hi all,
do also consider your usage pattern.

if you turn them on and off very often but duration is short, LED may be better as it lights up faster. LED has the disadvantage of having a lower lifespan for the same number of hours it is turned on.
on the other hand, if the application is used for hours every stretch, the energy-saving light will have an advantage in lasting longer.

ya, i put T5 in the lightbox only..and bedhead also..

I have no knowledge about T5, isit energy efficient or makan electric one...and is it durable ?

It is energy efficient. Its brighter than pendaflour lamp.

energy saving more efficient or T5 ? owh i thought it is same with pendaflour lamp

Pendaflour is energy efficient as compared to normal filament bulb. It is even power saving compared to CFL lamp. On top of the chart is of course LED, higher than that is sun light.

i have some extra led bulb e27 9w..if interested view my thread...

LED downlight




4" ----------- RM 40
6" ----------- RM 50

Ohh very cheap.. from China? What's the warranty?

Yes from china one year warranty, high quality LED. No jokes

can someone plz explain what is t4 n t5?

What is the brightness per watt? Lumens/watt

Sometime it look like good replacement, but when put into replacement the performance does not meet up. For new installation is easier, just put more lighting Source. Eg for normal cfl the area need 4 downlight, with led will need 6.

t4 and t5 flourescent tubes are differentiated by the diameter - t4=1/2", t5=5/8". The normal T8 flourescent tubes which we normally use is 1". See this site :http://en.wikipedia.org/wiki/Fluorescent-lamp_formats.
Nowadays, a lot of manufacturers are switching to T5 flourescent lamps for more energy efficiency(completes with electronic ballast fitting). T4 is being phased out coz there is no standard length, thus every manufacturers has their own specs. T5 lamps follows a certain specs, thus replacement is easy, just like the good ol' T8 .
Now, everyone is switching to T5 LED, but we have to note that this is still at a premature stage, as there is no concrete tests that the LED is outright better in terms of efficiency and cost-savings than the T5 flourescent. Just have to remember that LED is high investment costs(for good brands), but whether the ROI is as good as the manufacturer claims,
Cheers...

The lumen for 9 w of LED downlight is 850lm which is a 20 w cfl bulb for 12 w of LED downlight the lumen is around 1100lm. it brighter than a PHILIPS tornado 24W chl bulb.

if you are somewhere around kajang,serdang, cyberjaya or kepong or kl, kedah(sungai Petani) we can meet up.

9W LED = 850lm and with that price, you can go beat philip already. Even better than the Philips LUXEON I am having.

I don't need any LED now, as my house already using CFL, and T5 which i find is much brighter than the LED I can afford during renovation.

The price for this LED is not bulb, it comes with the complete set with driver and casing


If for the philips brand it will cost around RM130 per set.

This LED T5 tube is 80 % brighter than a normal T5.
one year warranty. RM 50 for 4ft
