Suits Hi-Par and other Ceramic Metal Halide (CMH) ballasts

These state-of-the-art lamps generate a greater level of useable plant light (photosynthetically active radiation) and run with a blinding intensity that's immediately apparent to the naked eye. The lamp is full-spectrum so it will produce the goods in both veg and flower – expect to see increased growth rates, tighter internodes, an improvement in overall vigour and an increase in final weight.

• Philips CDM-TP 315w/930 – full spectrum lamp
• A blinding intensity that's clearly visable with the naked eye
• Ideal as both supplementary and standalone lighting
• Highly efficient - puts out 1.9 micromole (umol) per watt of electricity
• Extremely high PAR levels

How this Product Works:

Because its full-spectrum, it's also great for the vegetative stages, triggering rapid growth, speeding up turnover times and increasing the overall efficiency of your indoor garden. With a healthy level of blue/white light (at roughly 5000k to 6000k) internodes stay nice and tight, eliminating the issues with stretch that occur when using lighting with narrow, inadequate spectrums. Ceramic-discharge metal halide lamps to produce a light spectrum that's much broader than other forms of HID lighting (like standard metal halides and HPS). Its output is more comparable to the light produced by LEP (light emitting plasma) units. LEPs actually have a slightly broader spectrum than the CDM fixture, but they simply do not compare in terms of brightness.

Using the Philips Master GreenPower 315W CDM Lamp:

Hold with a clean cloth and screw the lamp into the bulb-holder fitting of your reflector until it will turn no further. It is important that the lamp is screwed very firmly into the holder. Failure to fit the lamp tightly will cause arcing inside the holder between the centre connector and the contact on the lamp. This will melt the solder contact on the lamp and irreparably damage it. Ensure the lamp is completely clean and free of dirt, grease and finger-prints etc. before switching it on.

Warning: When HID lamps are switched on they run extremely hot. As with all high-pressure sodium and metal halide bulbs it is necessary to avoid touching the lamp with anything such as fingers or plants as this may cause severe burns or fires. In particular avoid sprays or liquids coming into contact with the lamp as this may cause premature failure or even an explosion.

As with all lamps the light output they produce will decrease with use over time. One Stop Grow Shop recommends you replace your lamp regularly to maintain your garden efficiency.
