Here we go again, Basement Bob is telling lies and misleading people for his own gain. Bob has never used any of Grobal Distributors products. If he had he would know that our ballasts are a LOW FREQUENCY, SQUARE WAVE BALLAST. That is why the On-PAR 315 CMH comes with a 5' reflector cord.
He is correct that Summit uses a high frequecy ballast. He also hasn't used there ballast, just check his other posts were he admits that Summit wanted too much $ so he didn't buy them. He has only used the DNA ballast with Irradiator hoods and the LEC.
The truth is that he is getting a kickback from grow stores for sending them customers. Just see the quote below.
Grobal Distributors provides a complete plug and play package called the On-PAR 315 CMH based around the 315 watt Agro bulb by Philips. It combines the efficency of the Agro bulb with our proprietary reflector design and digital ballast technology. All of our products are UL or ETL certified for saftey.
