  • Candela plot for G4 LED bulb


This bulb uses the latest Tesla Chip-On-Board LED emitter, which blasts out 190 real-world lumens in a tiny G4 format bulb. It is fully waterproof using a special thermal silicone with super-high refractivity. This allows for a nearly perfect distribution of light (see Candela plot pic).  

The main advantage of COB technology is that it allows for a bright and large LED emitter surface area without external heatsinks, which gives a fantastic color and a much less dazzling look than traditional LEDs. Our frosted silicone molding not only protects the bulb, but it also diffuses the light for a much more pleasant output.

    Consistently pleasing and dimmable warm light

    Posted by Richard H. on 19th May 2017

    We converted to LED lights in 2012 and ended up with a hodgepodge of different hues, some warm but mostly cool white. Replacing them all with these bulbs has transformed the atmosphere in the boat. The galley is less harsh and more pleasant to work in. The staterooms are more inviting. The salon has a dimmer switch and quickly morphs from mood lighting for cocktails to all-round illumination that's great for playing games. Plus, buying a quantity means this product is both cheaper and way better than what I installed five years ago.
