Oh ,yes ,of course it also relates directly to the 'cooling' issue ...Thanks,
Lower probably also plays a role in not needing fans

I think SupraSPL ,Guod , Mr Flux .....Amazing Work! thanks a lot to share!
I want to test in my prototype lamp this type of COB.I have right now 2x meanwell LPF-60D-54(1.12A) and 2x LPF-40D-36(1.12A) dimmable with pot 100k.
The 60D at max make 68W, the 40D at max make 47W, both tested after 24 hours of continuous stay realy cool in a sistem with 32 luxeon rebel best bin in 2 separate chanel with 12" fan at 64cfm with little fischer 160x200x25.
The lamp at max power after 24 hours continuos stay stable at 30°C.
The heatsink simulator, in this case, make wrong result: it supposes 43°C.
Do you think it's possible to use this combination of cob and meanwell?
Which COB I can use for my meanwell?
I see the CXA3590-0000-000R0YZ40E7 1.2 A - 77 V - CRI 93...
I know the power it's undersized,but it is for idro-microgrow with little problem in water temp that right now it's not risolved, and I don't know how.
A) Depends ...From four CXA 3070 (or more if driven softer / more efficiently ) to 'replace' a 400 W HPS .Great project sds...I think it is time for a patent!
The biggest question (in my mind) is how many of those high power leds you need to replace a hps 600 w or 1000 w bulb. There are a lot of led-sellers who exaggerate the performance of their leds what results in dissapointing grows/results, so I have read.
On youtube there is a guy that has a side by side grow of AT600 vs 1000HPS. Latest video was made on day 56. It looks very promising.
Yeap !So that was a loose wire in the fan?
That is what I heard. A wire hitting a fan blade. Had it happen in my PC tower builds more than once.
I thought that there were going to be sparks along with a fire after the dire description you offered.
Sound suppression ...Whats the foam pieces for on the sides of the fans on the top panel?
