Luxx Lighting CMH Grow Light Bulb, 315 Watt, Flowering Bulb (3100K)

Ceramic metal halide (CMH) grow lights are a relatively new type of HID lighting, and outperform traditional MH and HPS grow lights. The composition of these lights result in a far more efficient operation, a fuller spectrum of light, and lower heat output. These lights are generally more expensive, but pay for themselves in energy cost savings. Many growers are upgrading their standard HID system with a new CMH system for these reasons.

  • Full spectrum 3100k or 4200k
  • Superior color quality
  • Reduced operating heat

What does CMH stand for in grow lighting? (Definition & Benefits)

CMH stands for Ceramic Metal Halide, a type of metal-halide lamp that's also known as a Ceramic Discharge Metal-Halide (CDM) lamp. CMH lamps are often used as grow lights for indoor plants and have several advantages over traditional HID bulbs, including:

  • Color rendition - CMH lamps produce a bluish light with a color rendering index (CRI) of up to 96, which is similar to daylight. Some manufacturers say that the ceramic tube in CMH lamps, usually made of sintered alumina, allows for higher arc tube temperatures, which results in better color stability.
  • Efficiency - CMH lamps are 10–20% more efficient than traditional quartz metal halide lamps and use 20% of the power of incandescent bulbs with the same output.
  • Light quality - CMH lamps have a balanced spectrum and retain their color spectrum better than most other gas discharge lamps.
  • Heat output - CMH lamps produce low heat output, which can be beneficial in larger, taller spaces where increased ceiling height allows for better heat management and air flow.
  • Light intensity - CMH grow lights can produce more intense light than LED grow lights, which can be important for canopy penetration.

Product was as described and meet my need for a scale measuring 0.1 g
Color: Black
Product was as described. Works well. I use it for measuring the amount of coffee for my drip coffee maker. I have not done any testing with respect to actual accuracy so cannot comment. But it seems close to the other scale that I have that only measures to the nearest gram. Construction seems good. Nice looking unit.

Nice scale
Color: Black
Works as expected, nice size. Makes a big difference when adjusting espresso extraction. I haven't used the timer. One improvement for my use would be to move the power switch from the back to the front, on the side or on the control panel.
