Stage lamp for theatre rigs
The BTI 20R-C-440W is a 440 W standard bulb built for stage and studio fixtures. It supplies the high output that follow-spots, moving heads and fresnels demand during live shows or broadcast work.
Direct replacement in compatible sockets
The lamp seats in the designated 20R base without tools, so changeovers between acts are quick. Verify the fixture’s wattage rating and ventilation before fitting; exceeding the housing limits causes early failure and can damage the reflector.
