UV LED vs UV lamps

UV LED light sources are encroaching on application areas currently home to conventional medium-pressure mercury lamps. Differences arise as a result of the various technologies used for generating the light, as compared in the following table:

	UV LED	UV classic
Spectrum	“Narrow band” 365 / 375 / 385 / 395 nm	Broadband spectrum 200 - 440 nm
Efficiency	5 - 25%	25 - 30%
Service life	Expected: higher	Expected: lower
Temperature influence	Lower	Higher
Variable format lamp	Yes	No
Immediate activation	Yes	No
Run-up time	No	Yes (2 minutes)
Dimming range	0 - 100%	20 - 100%
Energy consumption	Chemical-dependent	Chemical-dependent
Mercury	No	Yes
Ozone generation	No	Yes/No
Exhaust air ducting	No	Yes
Size	Smaller	Bigger
Chemical availability	Lower	Higher
Distance dependency	Higher	Lower
Spectrum change	Complicated	Simple
