The LUMII Solar 315W CDM Fixture is a complete fixture that powers a 315W Ceramic Discharge Metal-Halide lamp(CDM) that will give your plants the best possible spectrum of light. Providing a closer more natural sunlight the full fixture unit is suitable for 1 x Lumii Solar GRO (Veg Stage) or Lumii Solar PRO (Flowering Stage) CDM Lamps.


  • Full Fixture – ballast & reflector
  • State of the art ballast technology, including soft start
  • Ideal as both supplementary and standalone lighting
  • Extremely high PAR levels
  • Highly efficient
  • Short Circuit Protection
  • Voltage – 240v
  • Amps -2.61/1.31
  • Dimensions: 41.5cm x 15.5cm x 18cm
  • Weight: 3.8Kg


PLEASE NOTE: No bulb included with this Fixture.



Provide broadest spectrum:

Ceramic metal halide lamps work by heating up a ceramic tube within the bulb. Ceramic can withstand much higher temperatures than other media typically used in lights. This higher temperature results in the bulb creating a plasma-like light source similar to the sun.

Since the light emitted from a CMH is akin to natural sunlight, its spectrum is closer to that of natural sunlight, so that plants exposed to CMH light are getting a wider range of wavelengths of usable light than other types of grow lights can produce.


Best CRI color rendering index:

CMH lights provide the highest measures of color rendering index (CRI) as compared to other grow lights. Objects that are fully visible in natural, unobstructed light appear to the human eye with a CRI of 100.

Artificial lighting does not reproduce the same light as the sun, but CMH bulbs come very close, with CRI ratings ranging between a low of 80 to a high of 96.


Provide UV Lighting:

CMH bulbs, as a function of offering a fuller spectrum of light, provide significantly more ultraviolet light than many other types of grow lights. Plants thrive during their vegetative stages with this type of light and it aids in the development of stronger branches.


Color Stability:

Unlike various other types of grow lights, CMH bulbs provide a consistent quality and duration of light throughout their useful life. Many types of grow lights lose effectiveness over time that may not be evident to the human eye; CMH bulbs retain their wide spectrum.


More Efficient:

This is subject depending on what is being compared and for the duration that the bulb is in use, but CMH bulbs are up to 20 per cent more efficient than other types of metal halide bulbs. The yield per watt of CMH bulbs is higher.


Longer Lasting:

This is another subjective benefit, but CMH bulbs do last longer than halogen and incandescent lights. They have been confirmed to run as long as 24,000 hours (almost 3 years).


Produce Less Heat:

Though they operate at higher temperatures, CMH bulbs emit less heat than other types of bulbs. This is important in smaller grow rooms, where a grow light may contribute to temperatures that are too high for efficient growth and yields.

It also means that the bulb itself can be closer to the plant, reducing the chance of burning the leaves which is a possibility with some other types of grow lights.


No Electromagnetic Interference:

The ceramic in CMH bulbs does not interfere with electronics such as cell phones or television signals the way that some other types of grow lights or electronic ballasts can. This is not only a convenience, but helps to avoid detection if the intent of a grow room is to keep a low profile.


Warranty: The LUMii SOLAR Fixtures are supplied with a 1 year warranty.

This is the latest lighting technology. Please note: a single 315w CDM grow light will not yield as high as a 600w HPS grow light and so you will need to purchase two CDM’s as a swap-out for a single 600w HPS grow light, but as with many things in an ever demanding world, quality usually has a higher worth, and so the cost outlay of upgrading your lighting equipment should be negated by the worth of a quality increase!
