The EvoluChem™ LED spotlights are designed specifically for photocatalytic, photochemistry or photobiology applications. They fit the PhotoRedOx Box™ Single HCK1006-01-016, PhotoRedOx Box™ Duo HCK1006-01-023, PhotoRedOx Box™ TC HCK1006-01-025 and PhotoRedOx Box™ UV/Vis HCK1022-01-001. Note that LEDs lower than 365 nm work only with the PhotoRedOx Box™ UV/Vis. They are designed to irradiate all samples with maximum efficiency compared to higher power LED light sources from the competition. They are more than 20 specific wavelengths ranging from 254 nm to 808 nm. This LED light wavelength is 450 nm with an irradiance of 328 mW/cm2 at 2 cm. The beam angle is 25 Degrees. The intensity can be controlled by an external dimmer or by the PhotoRedOx Box™UV/Vis HCK1022-01-001. You may need to order a power cord HCK1006-01-034
