I was searching for a full-spectrum lamp for my home office where I could get ideally 10,000lux of sun-replicating light, without having the lamp in front of my face to achieve that intensity (like with SAD lamps).
As bulbs/strips with quality LEDs (sunlike, bridgelux thrive/vesta, optisolis..) are weak and have questionable heatsinking (frying at 100+ degrees C), I now have DIY LED U-HOME 100W COB on the way.
Since I've never DIY'ed a LED before, could you help me out regarding what additional parts do I need - do keep in mind I'm from EU.
I believe I also need:
LED constant current driver - the manufacturer says 36V and 2.8A.
Mean well HLG-C doesn't seem to fit since 120W variant is only up to 1.4A, and more powerful variants are too expensive to get 2.8A
lens: do I need a lens, what difference does it make?
dimming - in case of Mean Well HLG/ELG, PWM or 0-10V or resistance -> 100k log pot connected like this should work?
thermal paste or thermal pad?
wire between driver and LED
LED COB holder -> is there a solderless holder for this chip to avoid soldering? Only thing I know COB is 28x28mm
heatsink -> no idea especially how much °C/W, passive cooling is preferred if it doesn't break the bank (40€ budget for the heatsink). Some have pre-drilled holes for specific COB models, holes for lens...
Also, can someone explain me the difference between dimming a 2.8A CC driver VS using 1.4A CC driver at full power? It seems HLG/ELG drivers dim via current reduction so the effect should be the same?
