If you are really looking for an ultra-bright LED replacement for a G4 halogen, you have found it. At 250 lumens, this is our brightest side-pin G4 LED bulb with 21 high-efficacy surface-mount LEDs spread over a 45mm (1.8") diameter. The LEDs cover a wide area, which makes it a great choice for reading lights and other big fixtures which use G4 bulbs.
As with all of our G4's, the 21-LED features Marinebeam's integrated constant- current driver, thermal foldback fuse to avoid overheating, and transient voltage surge protection technology. Transients can occur with static discharge or during load-dump events on-board, such as shutting down an inverter suddenly with AC loads still operating.
Not recommended for small puck lights.

These lamps are bright and perfect halogen replacements. And, the usual great service from Marine Beam!
The 21 LED Back pin G4, was a great replacement to the existing 20W Halogen. Nice and bright and is cool to the touch.
Marine Beam has the knowledge!
Brightest led bulbs I could find
Great product and quality.
G-4 20 Watt Replacement
I really like these lights, but don't think that you can just put them in your existing dome lights and get away with it. I thought they would be a simple swap out, being advertised as G4 replacement for 20 watt halogen, as that is what I was doing. However, due the size of the LED disk, mine would not go all the way into the socket. The fiberglass disc hits where the dome begins tapering before being seated. I guess an alternative would be a smaller light, but I like the brightness of these 21 diode lights. I don't really like returning things, and I like them, so I just brought them back to the shop to sand at the edges off to a point where they went into the socket deep enough to seat. You could ruin the lights, It is a little tricky avoiding the diode & resistor and the other two solder contacts.
