Description Philips Master Colour 315W Use the Philips 315W CDM lamp to improve everything in your garden! It produces a much wider CRI compared to traditional HPS lamps; CDM’s are 90% CRO while HPS lamps are around 30-40%. This increase in light spectrum helps to decrease internodal gaps, decrease the rate of stretch, increase essential oil production, increase the number of flower sites and increase growth rates. With one of the highest µmol outputs, coupled with a high sustaining lumen maintenance, these lamps will not only improve the end results of your crop, but they will also only need replacing after two years of constant use. They don’t produce as much heat as a standard 400W HPS, so adding them to an existing lighting set-up won’t affect the environment temperature or humidity too much. These lamps must only be used with the specific 315W low frequency ballast, with the correct light fitting. To aid installation, we can provide an adapter to retrofit your existing reflectors (E40 to CDM adapter)
