Description

The Digilight daylight 315w focus kit uses a Ceramic Metal Halide (CDM/ CMH/ LEC) bulb to deliver a full spectrum of light to your plants. We ship your choice of Philips MASTERColour bulb with these kits, that produces a white light very similar to the sun, including UV rays which will shorten internodal distance at the start of flower and increase quality towards the end of a cycle. You can choose between a red (930) and a blue (942) bulb – both have a high colour rendering index (CRI) and produce light similar to the sun.


With a CRI of 93, the light produced by these bulbs is extremely close to the spectrum of sunlight we receive. This balanced light will produce additional lateral branches, smaller internodal spacing, a larger root system and more, larger flowering sites. The 942 (blue) bulb is suited for vegetative growth whilst the 930 (red) bulb is suited for floral growth. A mix of the two bulbs in rooms with multiple fixtures will always have better results than a room using one type.


The Focus reflector is specifically developed for 315w CMH lamps to evenly beam light directly downwards in a 1.2m x 1.2m square footprint. You can fill as many 1.2m square spaces as you need with one focus reflector in the centre of each square. The CMH lamp produces a lot less heat than 600w HPS or MH lamps so you can get the lamps a lot closer to the canopy without heat burn. This will enable a lot more of the light produced by the lamp to be delivered to plants as the intensity of light quickly diminishes the further from the source the measurement is taken – the principle of the inverse square law. The graph below shows the intensity of light over a 1.2m x 1.2m footprint

The Focus connect is a compact unit that allows the ballast to be directly attached to the reflector. It’s attractive, compact and the fact the ballast and reflector are joined means it’s easy to install, take down or move.


We find that an increasing number of growers are switching their flower rooms and tents over to 315w CDM lights with focus reflectors and removing 600w HPS fixtures. 315w CDM units are much more efficient so will save on your electrical costs, produce less heat, can be placed closer to the canopy and produce a more rounded spectrum of light than traditional 600w fixtures. All these benefits of CDM fixtures over traditional lighting lead to larger, higher quality yields. If using these CDM lights exclusively, use a 930 agro bulb that has more reds in the spectrum, promoting heavier flowers and fruiting sets. Both varieties of replacement bulbs can be found here


If you choose to take the plunge and convert your room to 315w CDM bulbs, it’s recommended to use the 930 red bulbs in the focus units while simultaneously using horizon reflectors with 942 blue lamps as supplementary lights to provide an even spread of light. Use one horizon for every two focus reflectors for the perfect mix of spectral output and an extremely uniform spread of light.


You can run a maxibright Digilight daylight connect reflector with the ballast outside the grow-space, all you need is an extra IEC extension lead with one male IEC and one female IEC at either end. Make sure you get a length of cable that’s long enough to reach from where your light is to where you want to place your ballasts.


when you first switch on your 315w lighting kit, make sure you leave it on for at least 15 minutes to let the mix of metals inside the lamp properly fuse. Failure to properly ‘bed’ your lamp will result in the warranty being voided and could lead to the lamp failing.


If you’re having trouble installing your lamp into the reflector, make sure that it’s around the correct way as one of the connections is a different shape, preventing the lamp from being installed incorrectly.
