Description

Latest Technology for HID lighting

The Red 3k Lamp is perfect for all round growth and producing profuse, abundant flowersets. It produces 580 μmol of Par or 37000 Lumens


The Blue 4k Lamp is suited for vegetative growth and supplementing HPS lights. It produces 540μmol of PAR or 33000 Lumens

Perfect to cover a 1 x 1m footprint, CMH lighting is more efficient while creating a fuller spectrum of light than traditional plant lighting. While the initial cost is a bit more than HID fixtures, the benefits are noticeable in terms of the end yield quality and quantity.


There are two main things to consider when purchasing a light: Intensity and spectrum. If light were Human food, Intensity can be compared with the amount of food whilst the spectrum is like how healthy the food is. Lighting that outputs a narrow spectrum but with a high intensity (like traditional HPS lights) is like eating a load of fast food – It will sustain you but it’s not very healthy. CMH lighting is like a very balanced diet for your plants.


Both types of bulbs are extremely close to sunlight, with a near full spectrum, clear, crisp white light. The red bulb has a CRI of around 93 while the blue bulb has a CRI of 97. This denotes how close they are to sunlight, with full spectrum sunlight having a CRI of 100. Traditional HPS lamps have a CRI of below 30 because they mostly produce red, orange and yellow hues from the spectrum.


Ceramic metal halide bulbs use a different mix of metallic salts and halides than normal metal halide lamps which could corrode the arc tube if it was made from quartz or PCA. For this reason, the arc tube in CMH lamps is manufactured from ceramic which can withstand this new, innovative mix of compounds.


The salts and halides are in the perfect ratio to create a much fuller spectrum than traditional HID lighting, and the curve is much more continuous than LEDs, since LED grow lights often only output particular colours, with COB LED’s being an exception.


As well as the much fuller spectrum, CMH lighting has the added benefit of being super-efficient; producing many more photons per watt of electricity consumed than traditional HID fixtures. This means an increased yield for less expenditure on your electric bill.


Since CMH are dedicated horticultural bulbs, they have been designed with plant growth in mind. Not only is there a high output per watt in the PAR spectrum (photosynthetically active radiation) but there’s a significant UV output too, which is particularly useful for fruiting annuals that have evolved at high altitude as they are used to UV light in their natural environment. Expect Increased flavonoid and terpene production in aromatic plant species.


How to use

Bed the feet of the lamp into the holes on the lampholder on the reflector making sure the holes line up. Once the feet are in the holes, twist the lamp clockwise until it no longer turns, the fixture is then ready to grow!


315w CMH lamps should only be powered by ballasts designed for them that used low frequencies.


Never touch bulbs with your bare hands, use a cloth or gloves to protect the glass from oils and residues which can cause damage to the lamp or reduce its efficiency.


These Lamps have a PGZ fitting rather than the traditional E40 – You’ll need a reflector designed for use with 315w bulbs or purchase an adapter.


When you first fire-up your fixture, you need to allow it to run continuously for a minimum of 15 minutes to allow the metals and salts to properly fuse. If this is not followed, the lamp may fail.


CMH lamps take a lot longer before the efficiency starts to degrade when compared with traditional HID lighting. We recommend regularly replacing bulbs to maintain the efficiency of your garden.
