Here we have some special little lamps built using a dual LED to give an option for 0.5W or 2W depending on which side of the two pin base connectors is energised. The lamp body is negative and the base has two positive terminals to provide the option for two light levels.

An ideal lamp to use when dimming to a lower or power saving level is required. For those who are familiar with car lamps, it is basically a stop/tail lamp configuration but with a standard parallel pin BA15D fitting instead of the staggered pins (BAY15) as would be the case for a brake/stop lamp.

Excellent Warm White Coloration, nice and bright without any nasty blue content.
Suitable for use in 12v and 24v DC circuits. 
The lamps are approx. 45mm long (tip to tip).

THIS LISTING IS FOR TWO LAMPS AS IN THE IMAGES
