LED lights

are you counting dimensions by number of plants 6x4? plants vary in size, even autoflowers. 24 plants? 300 pounds ain't gonna do it. 60cm x 40 cm? Do you only grow autoflowers? That would be a different recommendation than if you plant to also grow photoperiods. For autos you want 500-600 umol/s per 1 m^2 of area - algebra can sove for your X m^2. Since your area of coverage was not accurately describes, this is the best way to explain it. For photoperiods you want 850-900 umol/s per m^2 - again, algebra can solve for X Assuming the light's specifications are accurate -- which is no gaurantee even with so-called reputable brands -- you can choose equipment that accurately fits your needs. ----------------- some nitty gritty that can help avoid garbage lights and recognize when they are lying through their teeth on the spec sheet.... if it's a samsun lm301-based light, there are some generalization you can apply to determine quality and if they are lying on spec sheets. All info can be compared to testing specs on samsung.com, which is accurate. e.g. any light promising "3.1umol/J" efficacy is fucking lying. No light is made with that diode and probably not running it at .2watts per diode as tested, either, if they are lying about stupid shit like that. So, in genearly, the more watts piped through a sammy lm301 diode the further it deviates from testing specs at samsung.com. divide watts by number of diodes and if it's significantly over .2watts per diodes, it's probably not a very efficient light. efficiency = longevity. Efficiency also saves on electricity, all other factors the same. Efficiency is what seperates a good light from one pretending to be a good light. .2-.3 is reasonable, but once you get to .4-.5w per diode it's 2x as much power as they are tested wiht.. so that so-called 50,000 hours of use is drastically reduced for those lights. (typically, hours of use indicates the point at which it will be 90% as bright as when it was new... which again is based on samsung.com testing... anything that deviates will reduce longevity)
