SunBlaster T5HO fixtures link together, regardless of length, to a maximum of eight per single power cord. It doesn't get easier or better than this. This reflector produces more light, spreads it wider across the plant canopy and deeper into the plant foliage, without consuming any additional power. The NanoTech T5 reflector captures 99.9% of previously lost light while increasing lumen availability up to 300%, with an average increase of available light of a whopping 48%.
