ha you guys are funny ok heres the sweet side life light systems are the best becuse, they are self cooled and you can have mulit spectem bulbs from sunpulse that are made for high frequncy ballast witch run alot more cheap sunpulselamps.com. you say the bend the light you are a dumb ass light moves a such a fast speed spinning at a fan rate will not mess up the speed of light get over your self. lls ( lifelightsystem.com) will grow the best pot you could ever imagein my brother has 2 2 arm 400watt each arm and a 4 arm 250 each arm, and a few other spinners but the point is his bud is some of the best bud i have ever smoked.
also buy spinning you increase the area your lights can grow, for example you may grow with one 1000watt and a hood witch gets hot and puts stress on your bulb witch shortens its life, you may grow one or 2 plants with about 5 oz a plant. with one 4 arm 250 you can grow about 8 plants with one lighting system with less enrgy than it would take with a bunch of hoods to grow 8 plants.
puls hps burn up and leak mucury on high frequncy ballast. so you have to use core & coil so you wasting enrgy. really check out the web site. hightimes did a center fill on the spinners they said they were the best i think so and sunpulse lamps are the best for e and d ballasts they come with 2 year warrnty its the lambo of the indoor hydroponics
