NEED ADVICE Which one is best for 4x4 tent? Down to these models, if theres another model that's good and same price range, let me know. Thanks in adv

the easy grow is 10x the light of mars or vipra.. Samsung LM301B (or 301H - EXACT same thng, don't overpay for H) are the best white led diode out there. it also has some red wavelengths. The only concern i'd have is heat dissipation - still far better than the other 2 options you list. you will likely save money in electricity within 1-2 years that will more than cover any difference in upfront cost. the efficacy of the easy grow is likely 25-33% higher than the mars or vipra models.. they are junk, sorry to those reading that use them.. they are trash, don't buy mars, lol. i think vipra is same category of quality. as in - hot and inefficient and reach 80% intensity within 2-3 years. so, keep it cool, and that easy grow light will last ~5-7 years before it hits 80% intensity.. ignore the 100k hours they list, that's some bullsh%$t. 100k hours until it is 50% intense, maybe, if they used TV standards for measuring longevity and not growing lights (curve @ 80% not 50%). if it isn't cool to the touch while operating, or at least lukewarm, get a fan on it.. it'll add 1-2 years of life. That's the only concern after you see they use quality parts (LM301B)... how is the heat dissipation? if not decent, do something about it. QBs can cause hotspots too in light coverage, but still awesome options.
