For your convenience, we have compiled various festoon belt sets with warm LED bulbs on this page. Our festoon belts come with the sockets, the plug, sealing rings, and the end cap pre-assembled. Upon receiving your warm white festoon belt set, all that remains is to screw the bulbs into their sockets. All our LED bulbs have a virtually unbreakable polycarbonate cover and all our sturdy, black rubber belts are suitable for outdoor use. The light color of our bulbs is expressed in Kelvin. 2000 Kelvin (or 2000K) is 'extra' warm white. This is the equivalent of candlelight, where the light is softer and more yellow. 2650K is the color of an incandescent bulb, which is to say still warm white, but slightly less yellow in color. We sell roughly the same amount of both colors, and have received positive feedback on both. If you would like to achieve a soft, atmospheric light, the 0.7 watt bulbs in these sets are the perfect choice. On the other hand, if you would like to create a more effective lighting solution, we would advise our 2 watt bulbs. Our 1.5 watt bulbs sit somewhere in the middle, and create a soft, yet effective light. We also have dimmable bulbs with dimmer plugs, so that the entire product is plug and play.
