    Big COB Setup: the annoying question.

    if I can afford a suggestion, it could be interesting if you are in Italy: http://www.spectradesignlab.com/ you can use their solutions or ask or be offered a custom solution based on your production needs tending to your budget I hope it was useful

    the HLG-600H thread

    Thank you CobKits, in fact I had read this warning / limitation on your site and I was looking for confirmation in my set with 9 Vero29D. About the fuse speech, do you consider it valid or obsolete in front of a 36V driver wiring in parallel? I do not see many alternatives to drive 9xVero29D...

    the HLG-600H thread

    I bump this thread because I have similar question like goofy81 ask in 2016 about fuse and protection,if have sense. someone have test HLG-600H-36v and Vero29 D? my intention it's to put 9xVero29D on one HLG-600, it's possible to get 1850mA for cob? (Vero29D at Tc 25°c =37,2v : at Tc...

    Citizen CLU048-1216?

    a question, on simulator 1216 at 1750mA at Tc° 25C° = 35.8v it's possible to fit n.4 1216 on MeanWell HLG-240H-C1750B (143v not open)? 1216 x 4 = 35.8v X 4 = 143.2

    Anybody tried the ELG version of Meanwells, Rather than HLG...

    I use on 220v ELG-100-C1400B and ELG-240-C1400B,I can confirm the voltage in spec and they are very stable. The voltage are similar to HLG but not the same. The drivers can dimm from 0% to 100%, at 0% are completely off, different form HLG that can dimm from 10% to 100%. ELG-100-C1400B in my...

    Lens discoloring my heat sinks

    Hard anodizing produce 30 micron layer if you respect the righ time of the process, if you are under, near 5/10 micron, probably too fast process, and a thin layer in teory can do that type o damage on prolonged exposure to heat and light.

    Matching Drivers and COBs

    I suppose the same...with Vero 29 D > n.4 on HLG-240H-1750B kick to max 1050mA... like hardcap of the driver...

    Matching Drivers and COBs

    can anyone confirm that n.4 citi CLU048-1212C4-353M2K1 are fine for HLG-240H-1750B at max power? if i see simulator voltage at Tc 50° it's between 37.0 and 37.4v... on calculator total voltage Tj 50 = 147.92v thank you

    Vero 29 ?

    I'm tested HLG-240H-C1750B, can run only n.3 Vero29 gen7 to get 200 watt total at max, if you put n.4 Vero,the driver kick to 143/145watt total at max.

    Something is moving in Bridgelux,today,finally, the first page of VERO features updated with new data: - Market-leading efficacy, 155 to 177 lm/W typical - Lumen output: From 520 to 37,260 lumens

    Which is best red single color actually ?

    no doubt: Luxeon Rebel ES - 630nm - LXM2-PD01-0050 Luxeon Rebel ES - 660nm - LXM3-PD01-0300 single or array, search only this bin.

    the fan, is attacked at its dedicated small power supply. first check that the blades are in axis and revolve smoothly, then also that the supply wires (blue brown) are attacked and balances to wago connection, then checking the connections between fan and small power supply (4 pins connection)...
