This bulb is designed to be fully dimmable, but performance can vary based on the type of dimmer switch installed. Use a standard trailing-edge or leading-edge dimmer compatible with halogen loads.
It is strongly advised against. Skin oils can damage the glass and cause localized overheating, which significantly reduces the bulb's lifespan.
2900K indicates a warm white light, which is similar to traditional incandescent bulbs and creates a comfortable, yellow-tinted white light.
Yes, provided it is housed in a fixture specifically designed for outdoor use that protects the bulb from moisture and direct weather exposure.
This is a standard 118mm length bulb, which refers to the measurement from tip to tip including the ceramic contacts.
Ensure the bulb is fully seated in the R7S spring-loaded clips and verify that the fixture power connection is tight.
Check the circuit breaker and ensure the switch is functioning; verify the bulb is correctly oriented and making solid contact with both terminals.
Ensure the bulb was handled correctly and no oils from fingers remain on the glass; also check that the fixture is not subject to excessive vibration.
Installation of the R7S bulb is straightforward but requires attention to safety and cleanliness. Ensure the power is completely switched off at the mains before handling the fixture. When installing, hold the bulb by the ceramic ends rather than the glass tube; the oils from your skin can create hot spots on the quartz glass, which may lead to premature failure. If you accidentally touch the glass, clean it thoroughly with a lint-free cloth and isopropyl alcohol before turning the light on. Ensure the bulb is securely seated in the spring-loaded contacts of the R7S fitting to prevent flickering.
