This Opus Brand 4watt Red LED GLS lamp is a direct replacement for a traditional incandescent coloured bulb. It is ideal for applications such as decorative strings, festoons and Christmas trees. Each bulb is coated internally to prevent the colour fading over time. With a BC B22 Baynonet Cap type and a 15,000 hour life, these bulbs are also suitable for outdoor use when used in an IP65 rated fitted.
