Hello everyone, I'm not really keen to create new topic for asking this only.
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).

QUOTE(frostier @ Oct 31 2019, 08:21 AM) you can't compare this apple to apple 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(ozak @ Oct 31 2019, 08:50 AM) Go get this Philips ecofit 20W T8 Led. It have 2100l. It's almost equal to conventional 36W T8. The 6500k make you feel like 2700l.  Will keep that in mind. Cheers. |

Being potentially cheapskate here. Worth to get one of these? How would it fare against the Philip's? https://shopee.com.my/product/142282385/223...8912?smtt=0.0.9https://shopee.com.my/product/53595731/1042343553?smtt=0.0.9 |

QUOTE(frostier @ Nov 13 2019, 06:33 PM) It's entirely up to you. Never try those before. 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 One of them actually stated(on other product page, basically same item). >0.9 Think I'll take my chances. Probably one or two just to try out. This post has been edited by UnknownH: Nov 13 2019, 06:48 PM |
