The RETRO XP i3 400lm is no longer being made, this page is only for reference. With 500 units made, first available in 2006, this was the first high power LED bulb replacement unit. With hardly anyone using the traditional Oldham / Speleotechnics lamps anymore and the ambundance of off the shelf LED lamps I have stopped production. The unit has served it's purpose for 14 years. Thank you to all who have purchased it ! (01/01/2020).

Using the latest LED and electronics technology, this LED retro fit provides 400 lumens of light output and gives new life to your existing caplamp. It will work with almost any battery combination and will provide light output when normal bulbs will not even light up.

Installation into a caplamp is straight forward and can be carried out in less than 10 minutes using a small flat blade screw driver, full instructions are provided, no soldering or permanent modifications are required.

The lifetime of the unit is well over 20,000 hours, so bulb changing becomes a thing of the past. Light output is from 50 to 400 lumens with even the lowest setting being bright enough to use underground. Mode changing is carried out by turning the cap switch on and off quickly.

There are 4 different optics to choose from, if you want a spot beam, then 2 x 11° spots can be fitted, if you want something like the older version (Retro2) the a 11° spot and 13° deffuser is a good combination that also gives some spill for yourt feet. However if you want a more bigger flood then a 11° spot and 40° deffuser is the one to go for. Still not sure? Then consider getting additional optics and you can try the different cominations out. Additonal optics are £2.75 when ordered with the RETRO XP, other wise £3.25. For an idea of how the various optics look see: Beam Shots.

The RETRO XP provides full performance with voltage inputs from 2.3 - 6.0V. It will also work with single cell NiCD / NiMH's / Alkaline batteries at reduced light output. If used directly with a standard Oldham 4V 16Ahr battery the run times for the RETRO XP are approximately: Mode 1 (70lm) - 90 Hours, Mode 2 (185lm) - 42 Hours and Mode 4 (400lm) - 19 Hours.

The RETRO XP is a proven unique LED light and the ORIGINAL retro fit, which combines the proven ruggedness of the traditional caplamp with the latest technology.
