QUOTE(failed.hashcheck @ Jul 10 2018, 06:58 PM) If you are in serious retrofit campaign with extra budget, and want do it right; I would advise against installing Philips Ecofit. You will might end up with disappointingly dim room compared to previous fluorescent tube. You are right. Go for Master range Go for Philips MASTER instead. Its lot more efficient and produce better light quality. For comparison on (nominal) rated output: Philips Super80 (traditional, green cap premium fluorescent tube) 36w, 3200lm, 82 CRI Philips Ecofit 16w, 1600lm, 73 CRI Philips MAS LED HO(High output variant) 14w, 2100lm, 83 CRI Side by side comparison T8 840. MAS LED HO (left) Philips Super80, HF Ballast (Right). Dont have Ecofit tube at this moment but it perform worse than both on last comparison I made. ![]() MAS LED rated only 2100lm, but the apparent brightness is still higher than 3200lm traditional fluorescent, due to directional beam nature of LED light, which increase its delivered (effective) lumens. I can't say for other brand, but I believe they wold perform same or worse than Ecofit for the same nominal wattage. The catch is it is much more expensive, cheapest I get was RM42/unit (vs RM10/unit for Ecofit), and since this tube is not targeted for consumer, its rarely sold in retail shops nor in non-bulk units. Typical B50L70 is 30k hours for Master. Unless they change that since I left |

QUOTE(failed.hashcheck @ Jul 10 2018, 10:18 PM) For current generation of HO(high output) variant, yes. I stand corrected. You are right. Master to begin with was 40k and 50k. Only Essential TLED was rated at 30k.http://www.lighting.philips.com/main/prof/...9002_EU/product Don't think so. You only save 6w in this case. Unless you could really benefit from 83 CRI upgrade, its more economical to just stick with your existing tube. Latest batch I install now is rated for 50k hours Of course it is. "EMP starter" is just extra fabulous name for dummy starter. The inside is just simple wire loop. |

QUOTE(NoobHacker @ May 21 2019, 01:18 PM) Just went Puchong TK light. What they recommend is: Please consider Ledvance as well1. if you don't need fancy well known brands, use two side wiring 2. if only use well known brands like philips, use one side wiring. Bought one 20W philips for testing, cant see the difference with naked eyes. I didnt bypass the ballast so sometimes the led will flick quickly then turns on. Other than philips, every shop sells different brand for two side wiring tubes Japanese quality are no longer reliable like last time, since their production line is everywhere now, instead of japan only china brands are getting better since they really care about their brand name now, and they mostly manufactured in their own country & factory. |

QUOTE(mot88 @ May 24 2019, 08:19 AM) LedAvance is by Osram. The price is more expensive than Philips. On FSL,some said they are oem for Toshiba. The price sold by major department store is pricey. I gotten about rm10 each for 4ft in a local ligthing shop.FSL is 18w, 1800 lumens vs Philips (High Output) 20w, 2100 lumens. LEDvance no longer part of Osram. My 1st T8 led is FSL and since upgraded to Philips now. FSL is reliable, obviously not bright vs Philips HO. For slimline T8 led bracket, using Philips wiring setting, one can get from Houses of Ligthing in Puchong.Better quality than the generic rm5 one (they also selling generic one) but price is slightly above rm10 each. To me it's worth as bracket easily last more than 10 years. They owned by MLS from a China |

QUOTE(UnknownH @ Oct 30 2019, 08:34 PM) Hello everyone, I'm not really keen to create new topic for asking this only. you can't compare this apple to apple Which/what brand t8 led is comparable to conventional fluorescent t8 in term of brightness? I did try one of t8 led tubes from Mr DIY rated around 1700 lumens(not sure exact value, plus minus 100) and really obvious how dimmer it is compared to conventional one. Conventional t8 36W gives around 2600 lumens(at least Philip's). Conventional fluo T8 emit 360, which your 2600 lumen will need to cater for the optical/reflector loss. For LED T8, you can ask for 2100lumen or higher. |

QUOTE(UnknownH @ Nov 11 2019, 04:41 PM) Being potentially cheapskate here. It's entirely up to you. Never try those before. Worth to get one of these? How would it fare against the Philip's? https://shopee.com.my/product/142282385/223...8912?smtt=0.0.9 https://shopee.com.my/product/53595731/1042343553?smtt=0.0.9 1. You can't be sure of the safety of the product. Philips brand have better brand image, in the event there's product issue, they shall react on it. 2. None of the product states their PF, so if the product u purchase have very low PF, you will end up consume more energy. 3. i've installed LED from Philips for the last 6 years |
