I have to buy a new led

High,you need around 600w to get fat buds like you see others getting.Take no notice when you see LED 200w will replace 500w HID,Iits a lie.If anything the HID will out perform the LED in bud size.If you have good extraction to get rid of heat or its a big area then get a HID lamp.You can get a Ballast for around £60 then a metal halide bulb for veg is £25 and a HPS bulb for flower is £25.They do duel spectrum for veg and flower for £25 but I like to use a blue Metal for veg,its keeps them nice and compact.The red in the spectrum makes plants stretch.If money isn't an issue and you can't get rid of the heat with an extraction fan then I'd get 2 300w maxibright or Lumatek.Those new square shaped ones.It depends a lot on how much space you want to light.You see lots of people on here using 150w 200w LED but none of them will have fat buds,have a look.The Mars TSL 150w is around £120 on ebay but you'd need at least 3 of them but they're quality lights.Get one with the LEDs on real heatsink and not just a thin piece of metal like a lot of the mars.Hope that helps my friend.
