Welcome to H2GRO!
The LUMii Solar 315 is a complete fixture that power 315W ceramic discharge metal-halide (CDM) lamps to give plants the best possible spectrum of light.
Suitable for all CDM 315w lamps.
Please note that the bulbs / lamps are not included with the fixture and are available to purchase separately on our website.
Advantages of CDM
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 colour rendering index
CMH lights provide the highest measures of colour 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.
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.
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.
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.
