Specifications
These coloured energy saving PL lamp is ideal for any sort of bright coloured lamps, special effect lighting and party lighting,
If a building's indoor incandescent lamps are replaced by CFLs, the heat produced due to lighting will be reduced. At times when the building requires both heating and lighting, the heating system will make up the heat. If the building requires both illumination and cooling, then CFLs also reduce the load on the cooling system compared to incandescent lamps, resulting in two concurrent savings in electrical power. Overall energy cost saving depends on the climate; increased heating energy demand offsets some of the lighting energy saved.
A typical CFL is in the range of 17 to 21% efficient at converting electric power to radiant power based on 60 to 72 lumens per watt source efficacy, and 347 lumens per radiant watt luminous efficacy of radiation for a tri-phosphor spectrum. Because the eye's sensitivity changes with the wavelength, the output of lamps is commonly measured in lumens, a measure that accounts for the effect of the source's spectrum on the eye. The luminous efficacy of CFL sources is typically 60 to 72 lumens per watt, versus 8 to 17 lm/W for incandescent lamps.
