Buy yourself a quantum meter and see what's what from a foot away, dead center. That's the only way to tell.
khyberkitsune Reviewed by khyberkitsune on . RM's Bicolor DIY LED lamp vs a Commerical unit I have two DIY LED lamps that I am experimenting with. An all white one posted in another thread and this bi-color update to my first DIY LED. Originally it was a 20 watt (2 * 10w) 465nm seedling & veg lamp and I just finished adding 24 watts (8 X 3 watts) of deep red 660nm and 24 watts (8 X 3 watts) of royal blue 445nm. It is impossible to compare the brightness by eye alone because of the differing spectrums, LED wattages and spacing, but I would wager my 68w passive cooled is easily Rating: 5
