If you want to learn...then open your eyes, learn, and research.
SK gives you 400w...so show me where it cost you over 1000$ for a 400w cob panel build???
Now the real story for the actual listeners who want 2 times a SK for less than the SK in the first place...
12 cxb @43=516
3
hlg 240-1750 = 210
3 heatsink= 210
holders=25
fan=30
fan supply=5
Thermal pad= 5
Mics(screws, wire, wago's)2= 25
total of $1026...for literally more than 2 SK's worth of light.
And many of that can be found for less than I listed...all on the safe/expensive side of the estimate. Sinks are the only thing that might add up some additional shipping charges(~45$ for 3 sinks) so still under 1100 worst case scenario.
AGAIN...THIS IS TO BUILD A LIGHT THAT IS 2X AS POWERFUL(800w), as an SK. and being 25-35% more efficient too...so even 2 sk's isn't enough to compete.
Yep, PLC. They been in production, not a new light. 3070 and 3590 is why I showed a range for the cxb builds for each chip respectively. 3070's are still far more efficient than anything in the market. Only a 3-8% increase per watt that tested to go 3590. And per current is basically moot because of the slight voltage difference making different wattages per current, and in the end get the same output per current. With just a 5-10w difference in total pull based on build size. Cost of all components associated with the 3070 are cheaper than 3590, saving even more on the build throughout for many people.
