The diodes used in initial LED grow light designs were usually 1/3 watt to 1 watt in power. However, higher wattage diodes such as 3 watt and 5 watt diodes are now commonly used in LED grow lights. For highly compacted areas, COB chips between 10 watts and 100 watts can be used. Because of heat dissipation, these chips are often less efficient.
"However, 3 watt and even 5 watt LEDs are now commonly used in LED grow lights. LED grow lights are now being produced which exceed 1200 watts." In talking about 1, 3 or 5 watt LED grow lights, you mean individual LEDs. In talking about 1200 watt LED grow lights, you mean arrays of many LEDs. Is this what is meant?
The former sense is sometimes called luminous efficacy of radiation, [4] and the latter luminous efficacy of a light source [5] or overall luminous efficacy. [ 6 ] [ 7 ] Not all wavelengths of light are equally visible, or equally effective at stimulating human vision, due to the spectral sensitivity of the human eye ; radiation in the infrared ...
Streetlamp with a ceramic metal halide bulb Ceramic metal halide bulb with G12 socket. A ceramic metal-halide lamp (CMH), also generically known as a ceramic discharge metal-halide (CDM) lamp, [1] is a type of metal-halide lamp that is 10–20% more efficient than the traditional quartz metal halide [2] and produces a superior color rendition (80-96 CRI).
They appeared to respond to a light being switched on and off, and to verbal or radio messages. The final results of this project were documented in the 1981 book, Project Identification: The first Scientific Study of UFO Phenomena. Rutledge died on Monday, June 5, 2006 at the Missouri Veterans Home aged 80. [2]
