The OSRAM COOL BLUE (W5W) 501 bulbs emit a crisp and clear white light with through blue tinted glass and is the original product supplied by Osram.

The inclusion of Halogen gas within these Osram Cool Blue 501 bulbs ensures the bulb projects a powerful and clear light, whilst the blue tint enables these 501 bulbs to produce a much crisper and whiter light, which is distinctive and removes the yellow tinge that is often seen in standard sidelight bulbs.

These bulbs should not be mixed up with the HALOGEN VERSION of the Cool Blue 501 (W5W) which is also available
