"The UniBulb infra-red heater lamp bulb combines radiant heat with warm white light in a single 250W bulb. Fitted with an E27 screw cap, it delivers 1300 lumens at 2700K and suits settings where both directed warmth and gentle illumination are required, including domestic and commercial interiors. This bulb is suitable for use in compatible heat lamp or reflector fittings and can be used in conservatories, bathrooms, animal enclosures and food service areas. The infra-red output provides concentrated heat, while the warm white light offers a softer appearance than harsher task lighting.
