just comparing the exposure values for fun on my mounted camera, dual bloomspects at 270 watts had a exposure time of 1/160s
Meanwhile quantum boards at 220 watts have a exposure time of 1/370s ! And thats not even matching the wattage of the bloomspects... same iso / f stop
This obviously doesnt compare par but i thought it was interesting nonetheless
Also the meanwell driver generates a fair bit of heat, keeping it outside of the tent is definitely a good idea
