The HLG 300L R SPEC Full Spectrum LED Grow Light has only been set up for a few days. Works great so far. All nodes are lite.

This light is awesome only using it at 30% and my plants love it. Hid are a thing of the past this thing makes a fraction of the heat and is much quieter than my old led that required massive fans.

Recently replaced a blurple with this bad Larry. Good lord this light rips! Fits perfect in my 4x4 with the carbon filter installed. Does warm up the tent a lil but I run em at night anyhow. Very pleased with my purchase.

I had the 4000k just got the 3000k for flowering same quality you would expect just a different range for flower once again still worth every penny for a small one plant op.
