WITH EXTRA LONG BACK PINS TO FIT EVEN THE DEEPEST FUNNEL-SHAPED CANTALUPI OVERHEAD FIXTURES
This bulb features a proprietary Constant Current driver and high-output thermally-efficient multi-emitter SMD LED bonded to an Alumicore substrate. These features combine to give record setting output, superior efficacy (lumens/watt), and the longest service life in a replacement G4 form factor. Great for bell shaped reading lamps and Cantalupi overhead recessed lights. Fits most boat and RV G4 halogen fixtures. Its 10 LED design spreads the LED emitters over a wide area, giving the bulb a pleasant tone, with a less dazzling appearance than some LED bulbs.

Fit check before ordering
G4 Bi-Pin LED Bulb - Back Pin Type should be matched to the existing fixture before ordering. The product name identifies the bulb or fixture family, but the final fit still depends on base, pin orientation, voltage, color, clearance, and the job the light performs.
| Check | Why it matters |
|---|---|
| Base or socket | G4, bayonet, wedge, festoon, MR11, and E26/E27 bases can look similar but fit differently. |
| Voltage and polarity | Marine DC systems vary, and some installations are sensitive to wiring, dimming, or polarity. |
| Color and use | Warm white, cool white, red, green, and dual-color options solve different cabin, cockpit, and navigation-light jobs. |
| Physical clearance | Tower, side-pin, back-pin, dome, and fixture housings can interfere with lenses or covers. |
Current selectable options

FAQ
Can I choose by bulb family alone?
No. Confirm the exact base, pin direction or offset, lens clearance, and color before ordering.
Is every LED suitable for a navigation light?
No. Navigation lights depend on fixture geometry, visibility sector, lens color, and output pattern. Use a navigation-specific bulb or fixture where required.
