CAUTION! This bulb could cause eye damage, as it seems to give out a lot of ultra-violet. NEVER water or mist near it as it could explode!! It's a 500 watt Mercury Blend Lamp balanced for vegetative growth nort flowering & was installed in my kitchen in October 2001. It's put on from about 8.00 a.m. & off at about 7.00 p.m. or later. I tend to switch it off if I am in the room. An oscillating fan is left on 24 hours a day. It gives out a lot of heat as well as light, heating my kitchen to 25° C or more even in winter.  Even P. reflexiflora is producing sturdy new growth & P. x belotii, P. 'Betsie Greijmans', P. bicornis, P. cinnabarina, P. colinvauxii, P. x colvilli, P. organensis & P. suberosa continue to flower. Some Passiflora are very tough so put them closest to the light. P. suberosa has grown right over the top of the reflector. I am very pleased with this light & would recommend it but watch out for pests & expect the plants to look straggly & flowering to reduce as winter progresses. Tacsonia & others that are more comfortable in lower light levels do better kept away from it. It is also too much for most seedlings.
