Hi Bobby, i saw some your posts on another forum where now you're banned. I'd really like to get from you an opinion about maen well hbg 100-48(A) driver VS hbg 60-1400. Both of them ar dimmable. 60-1400 is 1.4A, cheaper(cost half of the price)and ready to hanging but it hbg100 is 2A aloy and...

Hi, i'm not doubting in your words but as you can see heremouser says in item description: "Dimming: Without Dimming " http://www.mouser.it/ProductDetail/Mean-Well/HBG-60-1400/?qs=IL6XaBr%252b7X%252bRArKfe2Pabw%3D%3D and also in your link i could not see any dimming optiond that's the reason...

Hi, 50°C is a good value, if it is true that cree and other good COBs could run up to 80°c it is also true that for example with cxb3590 BD driving at 1.4A you would get at different temperature: 143.4 lm/w (48.8W)at 25°C 6998 Lm 136.8 lm/w (48.3W)at 50°C 6607 Lm 128.7 lm/w (47.7W)at...

Hi Sanjuan, thanx for hou kindly answer. Also with 152100 i'd keepthings easy, i simply would not waste money in an oversized heatsink, you know, best led cooling would be best light performance and you probably agree with me if you were choosing that instead of 134100,have you never took some...

Thanx, i'm really glad to heard it!

Hi again. What could you tell me about heat dissipation, is it a good alternative to classic active cooling lamps? I m looking after this setting and i don t know if may be a good idea choose the 134100 heatsink(0,67°C/w) for about 27 eur (no need adapting aloy play) or this (0,52 c/w)for about...

hi, the same thing may happens using the newest VERO29 gen.7? I have just see on Cree tools that at 60° cxb3590 has only 4% better efficency than cxb3070(top bin). No data about vero29gen7 at more than 25°C but that may show lower V so for example a Vero 29 at 60°C will run at 35V.. driving...

hi, long time i'm looking for that solution for my first DIY COB, it seems to be easier than all other for a complete newbie like me. Sorry for my bad english, i'd have some questions about your project. what size your heatsink is? 152mmx100mm or 152x150mm? I think the alloy plate may be...

seguo!

hello, i m from italy and i m tryng to make my first diy grow les...this is one of more interesting but because a 3 years ago 3d i m asking to you id do you still think that a red light supplelement to a cree cxb con should be useful. the red/uv/ir really our plant need them? and a second...
