This G4 LED bulb continues to be one of our best sellers because it fits most boat and RV G4 halogen fixtures, and is one of the brightest G4 LED replacements that we produce. Its 10 LED design spreads the LED emitters over a wider area, giving the bulb a pleasant tone, with a less dazzling appearance than some LED bulbs.
The 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.
The output of this bulb significantly exceeds that of a 10W halogen, and fits most fixtures, even the small puck lights and recessed fixtures used on most modern boats.
- 10 high-efficacy LED chips (low power, but super-bright)
- Thermally efficient PCB design for longer LED life
- No radio interference - CE EMC Approved
- High color rendering index (>85) in Warm White option
- Polymeric PTC re-settable thermal foldback fuse - protects the LEDs from overtemperature by reducing the current
- Transient Voltage Suppressor (TVS) - protects the bulb from momentary high-voltage spikes due to load-dump events from inverters, static electricity, etc.
- Polarity ambidextrous design (no polarity required)

I have used and tried many 12 volt LEDs over the years. These are the best I have found.
Good light output, and engineered to be safe at fluctuating voltages
Fast shipping, great company to deal with.
I purchased a motor home 10 years ago, and replaced most of the 10w Halogens with Marine Beam LEDs. The changing voltage in an RV as the batteries charge and discharge, is death to common LEDS. Marine Beam claimed that was not a problem for their bulbs, which has proven to be true. Most of those 10 year old bulbs are still doing their job. One failed after 8 years and another at about 9 years. As the remaining Halogens burned out I tried different LEDs form different companies. I bought two ten packs of for $16 each. Everyone of them began dimming and flickering after only a week,, and were dead in two weeks. I bought and installed new bulbs from Marine Beam. My motor home is now well illuminated, bright cool white in work areas, and warm white in relaxing areas. At any battery voltage, the lights seem to stay constant. There is no flickering.
Marine Beam bulbs cost more, but you get so much more in quality and consistency. One of the 10 LED MB bulbs is slightly less expensive than the 10 pack i mentioned earlier, however all ten of those bulbs failed in 5 weeks.
This is the second set of Bulbs I bought from this company. Truly excellent service and response to my needs. The bulbs are exactly what I need. They are of a higher quality the bulbs I am used to finding in the marine stores. I highly recommend this customer focused and friendly company.
I was talking with a fellow offshore cruiser about wanting a Red/White fixture for over the chart table. I was holding out because I really liked the current fixture and also having all my fixtures match. He excitedly showed me the MarineBeam Red/White bulb that worked off a single on/off switch. Amazing! The only problem is I have old fixtures that use the older bayonet style bulb, not the newer 2 pin G4 bulb. Turns out not a problem at all, MarineBeam sells the adapters!
What a great solution. I was able to put Red/White in my 2 heads,, my cabin, the galley, over the dinette as well as over the chart table. I have been using them for a few months now and they are great. The only minor issue is they were crooked in the fixture, but my fancy glass diffuser on the fixtures made it not noticeable. I loved the solution so much when my cheaper Amazon LEDs started flickering I oredered some white only G4s from MarineBeam instead of using the spares I had on hand.
Upon ordering the next batch of bulbs, I noticed a YouTube video on the Bayonet G4 adapter. I wondered what is so special about the adapter to warrant a video? I had to watch it to find out and was very pleasantly surprised! The bayonet swivels to make sure the G4 bulb faces downwards! I went in and readjusted all my current installations and love them even more!
