QUOTE(b0rhui @ Oct 3 2017, 11:13 PM) Dear all sifus here  I'd love to retrofit t8 led tubes into my existing magnetic ballast housing (with starter). From my understanding above, if I choose to go with philips ecofit 16w, the only option is method 1 removing the starter. But it has cons such as ballast going failure, ballast consuming more wattage. So if I wanna remove the ballast and rewire I have to get type A LED tubes, right? I currently use 10 x 18W T8 2ft tubes and 6 x 36W T8 4ft tubes. Would it actually be worthwhile to pay more for the LED tubes? the ballast is going to give you a headache when is spoilt, it causes your Electric Circuit Breaker tripped! best way is just mod your existing T8 Housing simply by removing the starter and ballast connection. wire LIVE and Neutral in opposite direction. there must be no connection in between this both T8 holder point! I do this method everytime cause i'm lazy to replace a new T8 housing which is thinner and less sturdy. Don't go with Philips EcoFit 16W and new cheap 18W LED around RM 6.90 is so dimmed is pretty useless. I'm currently using latest T8 LED 28Watt which cost around RM 16 - RM 25. The brightness is comparable or even way better than your fluorescent 36W tube. Dont skimp on wattage when they cant illuminate better than your existing fluorescent tube! |

The Philips Ecofit can be fitted without using the ballast. I have actually join the 2 wires connecting the ballast directly. However, the power saving from using the ballast and not using the ballast with the Ecofit LED lamp is negligible, in terms of mW.
I currently use 10 x 18W T8 2ft tubes and 6 x 36W T8 4ft tubes. Would it actually be worthwhile to pay more for the LED tubes? If you concern about the initial capital investment of the tubes, why don't you change the tubes only when it become faulty? Or only change the existing tubes that you switch on for long time daily to justify the cost.
By doing so, no wastage in term of the fluorescent tubes lying around and minus the RM11.50 per tube investment. Bear in mind the luminance of the LED tube is lower than the fluorescent tube but the power consumed is less than half the conventional tube. (16 W versus 40 W)
The reason everybody is going into LED tube is due to energy efficiency and less maintenance. You don't have to worry around 6 - 12 months problem whether is tube or starter or even worst, the ballast  Fluorescent tube problem is slow to turn up the light, blink once or twice before it shines. Where else the LED tube is turns on the spot. LED light has improved day by day. LED light is less prone to electric static interference too. |

QUOTE(flowerhorn08 @ Oct 5 2017, 12:30 PM) What brand is the T8 LED 28 W. Any recommendation where I can buy it at RM16? Can't recall the brand but the end plastic cover is gold colour not being white. Brand wasn't an issue, just get 24Watt or 28Watt. RM 16 I got in warehouse bulk |

QUOTE(flowerhorn08 @ Oct 6 2017, 10:50 AM) Gold end plastic....that's really a rare find. I guess it will be selling RM20 plus in retail. Gold or yellow end plastic to distinguish from standard ones. I even bought 24W for rm 25 each back in Kluang but roughly rm 20 ++ for brighter LED is acceptable. |
