Yesterday evening the new LED veg lights came in from Atreum Lighting, and this morning I went to work with a game plan for hanging them above the Veg ll tables. I wanted them adjustable but not swinging around like a swing set when being moved so a stationary design was in order.
Mike from Atreum told me these new 144.2 LED boards are based upon the tried and true Samsung LM-301b led chips, except unlike the 288.2 boards in the GR=1 flower room, these are 4k boards, giving a better spectrum for vegging and don't even require a heatsink. The jury is out on that one, but I'll run her through a series a hard tests. I'm curious to see what the temp on the aluminum backing runs at full operational temps.
I REALLY dig the new board connections. The connection is SO much better, and looks a lot easier to wire. I didn't receive the connector kit yet-It's due in Monday, but it looks about as plug and play for a DIY kit I've yet seen.
Our Veg ll tables are right at 75 inches long and 30 inches wide with each table holding a dozen plants in 5 gallon buckets. For a 400 canopy PAR, Atreum figured three of the 144.2 4k boards running at 48 volts and driven by one Meanwell 185 driver in what looks to be wired for a parallel board configuration.
One mistake I've seen HLG do is securing the driver to the heatsink for the LED's. Seems a bad way to pick up heat, and isolating those two components just makes sense. An air pocket between the two sure cant hurt.
The boards are right at 10.5"x10.5" and weigh very little so I opted to build the frame from 14 gauge 1/2" angle and spaced the lighting footprint equally across the table. I used 14 gauge 1x1 square tubing for the vertical supports and used slightly larger square tubing for the pocket and the adjustment sleeve. I welded a few 3/8" nuts to allow locking down the lights after height adjustment
The most exciting part of these lights, is the entire lighting above the 14 tables totals only 2590 watts! Not too shabby for driving 168 plants to the brink of flower...
