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. Unlike black light blue lamps, these lamps do not use wood's glass. They use regular soda-lime glass and emit more visible light than BLB lamps.
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
Ultra-high-performance lamp. An ultra-high-performance lamp, often known by the Philips trademark UHP, is a high-pressure mercury arc lamp. [1] These were originally known as ultra-high-pressure lamps, [2] [3] because the internal pressure can rise to as much as 200 atmospheres when the lamp reaches its operating temperature.
A blacklight, also called a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave ultraviolet light and very little visible light. [ 1 ] [ 2 ] [ 3 ] One type of lamp has a violet filter material, either on the bulb or in a separate glass filter in the lamp housing, which blocks most visible light and allows through UV ...
The amount of UV that is generated from a low-pressure lamp is highly dependent on the temperature in the tanning unit. As a rule, tanning lamps produce the highest amount of ultraviolet light when this temperature is between 90 and 110 °F (32 and 43 °C). As the temperature moves away from this range, the amount of UV produced is reduced.
These lamps emit ultraviolet light with two peaks in the UVC band at 253.7 nm and 185 nm due to the mercury within the lamp, as well as some visible light. From 85% to 90% of the UV produced by these lamps is at 253.7 nm, whereas only 5–10% is at 185 nm. [36] The fused quartz tube passes the 253.7 nm radiation but blocks the 185 nm wavelength.
