      Black Friday purchase , extreme deal

      I am using the hlg 600 h and a mars hydro 3000w in a 8x8 mars hydro tent for vegetation and seed propitiation. Hlg 600h was very easy to assemble. It did come with dimmer in box. Light is very bright on full power and useful on lower power for beginning plants out of propitiation dome. Very good value for money. Would buy again.

      So bright it hurts!

      Haven't had a chance to use the light with plants yet but my confidence is pretty high that it will do great things. Assembly was very easy using the video on this website only a couple basic tools were needed to complete the job. Got the dimmer and it works great with the system very impressed with the service of this company can't wait to get the light into action.
