T5 HO 2.0 4FT 4 Lamp LED Grow Light (216W Eqv.) – Sun White Pro Spectrum

Amazing Grow Lights

These grow lights are absolutely crushing it in regards to my seed starts. Over in cloudy Seattle we have lots of overcast days, and these lights have been a huge help in getting my garden growing! A huge upgrade off some cheap LED lights I bought a few years ago.

Successful retrofit

I had been looking around for a LED solution that would fit inside the adjustable fluorescent fixtures on my 4-level FloraLight unit which is at least 20 years old. After removing the old ballasts, wiring, and switches, then drilling some holes, the Active Grow 48" lights can be attached. I used eight 1/4" bolts with washers, but a dozen beefy sheet metal screws would probably work too. The result is lighter units that are easier to adjust up and down, more light, better light, less heat and no need to replace and recycle used fluorescent tubes. The only down sides are that the switches aren't quite as accessible, and the daisy chain outlet is blocked -- both minor matters which could be alleviated.
