There are lamps that are designed for operation in closed and enclosed fixtures. An added advantage of eliptical lamps compared with tubular lamps, and especially for the Osram HQI range, is that lamps can be used in universal position, opening many interior and exterior operation possibilities. Indoor lighting is mostly limited by requirements of hard to find electronic gear that eliminates flicker and improves lifetime as well as provide quick lamp restart. Conventional gear is available but hum, flicker, wiring complexity are unavoidable. | There are lamps that are designed for operation in closed and enclosed fixtures.

Coated lamps should be used where lamps are used in open fixtures due to less glare, while uncoated lamps are much more efficient in enclosed fixtures that almost always have reflectors or internal surfaces that help direct light. | |||
Lower rated power output gears can be used, but it is not recommended as colour reproduction and lamp lifetime will be reduced while higher powered ones damage the lamp due to over-stressing and is highly dangerous. Used lamp gears might work but old lamps are never desirable as they degrade much quicker than mercury vapour and sodium lamps. Rusted ballast may still operate but are a potential hazard while old, used lamps, may not have much useful life left and they may already exhibit some colour light emission issues. New old-stock lamps are the best choice, if available. | Lower rated power output gears can be used, but it is not recommended as colour reproduction and lamp lifetime will be reduced while higher powered ones damage the lamp due to over-stressing and is highly dangerous.
