HLG 550 or Spectrum King 600?

[Bluelotusrick]

Im starting a 4x8 grow tent and im planning on either getting the HLG 550s or the SK600s? The sk600s have a lot of reviews compared to the HLGs but the people that reviewed both say HLGs are better and more efficient. Do you guys have any opinion on these lights? Cheers

Anyone ever try the HLGs?

The hlg550 is newer. I just received 2 a couple weeks ago and I've been thoroughly impressed. Extremely bright but not too hot to touch.
from what I've found the hlg550 is a much better option than the sk600. Quite a but less money and more efficient. Win/win. 2.4um/j is no joke.

Yep, the HLG550 is no joke. Very efficient at producing plant growth. A couple of those units would rock your grow tent.
