At £1200 I'll give it a miss & go with the 600w HPS

Spectrum king aren't some cheap knock off led of old. They could definitely replace a 600hps, are more efficient, don't require as much cooling, nicer spectrum to work under, being a warm white colour. They are damn expensive though, but don't require regular bulb changes. 5 years of 6 monthly hps bulb changes is £300 and that's not even most optimal. Never mind reflector changes as they lose 10percent in reflective efficiency per year. Hps is s proven workhorse, it produces the yield and when used properly, cup winning weed. It's just not the future, which is solid state, full spectrum led all the way

i have one i just dont know wither to use it or not hahaha.. thanks for your responses guys! it looks like there is mixed opinions on leds

i found some info on the internet and it seems like hps have literally double the growing power but the king is way more efficient electric wise and like one of you said the leds in them last forever.. im still undecided haha. maybe i could use them in veg and then hps in flower?? hmmss just seems daft it sat here collecting dust. i normally use mh600w in veg
