found these on E-BAY https://www.ebay.com/itm/2xFull-Spectrum-47-LED-Grow-Light-T8-strip-Lamp-For-Hydroponic-Greenhouse-Plant/142946734854?epid=10018052179&hash=item21484a1306:g:~9oAAOSwmFhbpEDP they appear to be a mix of cool white and deep red leds with an efficiency of around 133LPW. they look like they may be useful as side lighting in a 2ft by 4ft tent. has anyone tried these? the SPD in the ad appears close to what nasa found to be the best spectrum for growing plants.I use T5s with added UV (uva plus bulb) but sativa s tend to grow tall and I would like a little side lighting with these strains
