so you just want one light unit ?
Like a hps you want a single box if you will with one plug and say just 1 "lamp" that emits light ?
A 1000w+ draw led single cob unit can be made
but the reason why a lot of led growers yield big is because the emitters are spread all around the grow and ran underrated this gives so many lighting angles and cuts out shade areas, giving more yield
Kinda like how some tube lamp growers claim to be out yielding hps growers also why grows with 6 or more 600w hps lamps over a large area seem to get way more gpw then a grow using one hps in a smaller space
but I do think you could still build a 600w or 1000w led unit that would have 1 to 6 emitters on it and match a hps
I would go for a 3000k unit for flowering as if your used to hps red or red/blue lamps can make it tricky to see your plants and see how they are doing
red light along side 3000k will add more yield but some strains grow a bit funny when you flood them with just red light, a lot take it well
So yeah 1st choice is if you want a huge panel with loads of 1w ot 3w or 5w led chips or a unit with 10 to 30 "cob" led chips
or you know a unit with 1 to 6 cob chips
or maybe you dream of a 1000w led chip in an aircooled hood ? maybe even side light with one too
some times with led the best part is you get more gpw and you get less heat so you can use 2000w of led where you could only use 1000w of hps before and yield more
some people just like it cos they can use less power, yield more and water less or use smaller pots and such, sometimes that`s a smart move too
Shop around LED`s and induction lamps have dropped in price a lot over that past few years
