Get a broad light spectrum and high PAR output from a single supplemental grow light – try our 315 Watt Maxibright CDM Euro Lighting System.

You fit it between 2 HID lights to get healthier, bushier plants with fruit and flowers that look, smell and taste better.

You get: 
315 Watt Philips CDM Lamp + 315 Watt Maxibright Daylight CDM Ballast + BAY6 Euro Reflector + CDM Lampholder

They’re low energy but ultra-bright, with a stupidly high PAR output  (up to 1.9 micromoles (µmol) per Watt!).  As for colour rendering, it’s fantastic – the ballast was made specifically to maximise the light's beam pattern and spectrum output.

Lamps consistently emit a broad light spectrum that’s much closer to actual sunlight to prevent stretching and enhance growth. The 930 Agro lamp’s spectrum is the closest one to actual sunlight we’ve ever seen!

As a result, plants form more lateral branches, have smaller internodal spacing, more flowering sites and larger root systems. Wait 'til you see the yield increase! Since plants will start producing more essential oils, your plants will look, smell and taste nicer too!

Don't worry about your energy bills & grow room temperature rising– remember, lamps are only 315W! For safety, lamps are double jacketed (bulb in a bulb).

• Best of both worlds! A Broad Light Spectrum & High PAR Output
• 315W Philips CDM Lamp + 315W Maxibright CDM Ballast + BAY6 Euro Reflector
• Cheap to run - low energy consumption – no abrupt power surges
• High output of up to 1.9 micromoles (µmol) per Watt
• Broader light spectrum: Fruit & flowers taste, smell & look better
• Accurate colour rendering for stable, crisp bright white light
• Use throughout vegetative growth & flowering
• Position it between two HID lights
• Can retrofit into existing set up

Simply position it between two HID light to broaden your light spectrum throughout your grow.

The Light Spectrum

The light spectrum is made up of different colours (or wavelengths).

For growth: 
Plants use wavelengths between 400nm - 700nm. These wavelengths are known as the PAR range. 

For quality:
They may not be used for growth, but wavelengths outside the PAR range (such as UV-A, UV-B, infrared and far red) are key to plant health.

• HID lamps: mostly emit wavelengths from inside the PAR range for growth
• LEP lamps: mostly emit wavelengths from outside the PAR range to enhance quality 
• CDM Lamps fall somewhere in between, and do both - they really enhances yield size and quality when used along side HID lights.

If you want to know how many particles of light (photons) from the PAR range are emitted by your lamp per second, you need to find out what its PPF reading is (measured in micromoles). 

1 micromole = 602 quadrillion particles of light from the PAR range.  

Remember, your PPF reading doesn't tell you how many particles of light from outside the PAR range are emitted by your light.

The 315 Watt Maxibright CDM Euro Lighting System is best used alongside your main grow lights as a supplemental grow light. You can retrofit it into your existing set up.

We recommend positioning it between two HID light to broaden your light spectrum throughout your grow.    

Inserting a CDM lamp into a CDM lampholder:

You will notice that the two pins at the bottom of the lamp each have a different end point - one being a complete circle and the other being a half circle. You must ensure that these match up with the corresponding grooves in the lampholder, as forcing them into the wrong place could cause irreversible damage.


These lamps can cause serious skin burn and eye inflammation from short wave ultraviolet radiation if the outer envelope of the lamp is broken or punctured. If using in an area where people will remain for more than a few minutes, make sure adequate shielding or other safety precautions are used.
