RETLUX RLL 457 R7S J78 4,5W LED COB WW

The Retlux RLL 457 LED bulb is an energy-saving replacement for classic 42W halogen bulbs. Thanks to its R7s base and tubular shape, it fits into light fittings designed for this standard. With a power consumption of just 4.5W, it provides a luminous flux of 500 lumens, which is equivalent to the older halogen version. It emits a warm white light with a temperature of 3000K, which is pleasant for living spaces. Its long lifespan of up to 15,000 hours reduces the frequency of replacements and saves on maintenance costs.

Wide Beam Angle and True Colour Rendering

The bulb uses COB (Chip on Board) technology, where the LED chips are concentrated in a small area to ensure uniform and intense light. This achieves a wide 270° beam angle, which effectively illuminates a larger area without dark spots. With a Colour Rendering Index value of 80 Ra, the colours of illuminated objects will look natural and undistorted. This combination of features makes it suitable for lighting living spaces where both the quality of light and its even distribution are important.
