Ficus plant grown under a white LED grow light. A grow light is an electric light that can help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated (typically a varying combination of red and blue light, which generally appears pink to purple to the human eye).
Significant peaks of UV light are present for CFL even if not visible. A photograph of various lamps illustrates the effect of color temperature differences. From left to right: • Compact Fluorescent (General Electric, 13 W, 6500 K) • Incandescent (Sylvania, 60 W, Extra Soft White) • Compact Fluorescent (Bright Effects, 15 W, 2644 K
Fluorescent lamps convert more of the input power to visible light than incandescent lamps. A typical 100 watt tungsten filament incandescent lamp may convert only 5% of its power input to visible white light (400–700 nm wavelength), whereas typical fluorescent lamps convert about 22% of the power input to visible white light.

These lamps are used for fluorescence effects where less visible light is ideal. 09 N/A Sun-tanning lamps: These lamps produce wide or narrow band UV-B radiation 10 BL Black-Light lamps: Black light lamps give off long-wave UV-A radiation of around 350-400 nm. They are often used to attract insects to traps.
A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...
One of the challenges is the development of more efficient green LEDs. The theoretical maximum for green LEDs is 683 lumens per watt but as of 2010 few green LEDs exceed even 100 lumens per watt. The blue and red LEDs approach their theoretical limits. [citation needed] Multicolor LEDs offer a means to form light of different colors.
