The Daylight 315 when used with the Philips CDM lamps ensures healthy abundant yields, excellent PAR output levels per watt of power consumed and delivers outstanding results at an affordable price.
Maxigrow has tested other recently released 315W ballasts. Our tests found that these ballasts do not run the Philips 315W Daylight lamps correctly; spectrum, performance and lamp life could be affected. We can only guarantee the Philips 315W lamps with the Maxibright Daylight 315 ballast.
