Just wanted to mention that the latest version of the Retro LED insert for Oldham, CEAG and Speleo-Technic caplamps is now available.
The new version has 3 modes of 70, 185 and 400lm, with very little additional power consumption compared to previous models. All due to the latest advances in LED efficiency.
Price is still £60.00 all in with delivery. For full details please see:
