LED Cap Lamp Lighting - New Version Available Now

I have designed a LED light which replaces the normal filament bulbs in a Oldham or Speleo-Technic cap lamp. It is electronically controlled so that it will work with any battery cell combination up to 6.0 Volts input, it is called the 'RETRO 2'. The first version used 2 x 1W Luxeon LED's each giving out 45 lumens, the latest version uses 2 x 1W Seoul P4 LED's each giving out 100 Lumens, a total of 200 Lumens which is really bright!

If you are interested in purchasing a unit then email me on the address shown in contact for Mike Hrybyk and I will contact you with ordering details. For questions you might want to ask, see the RETRO 2 FAQ's

Using the latest LED, power supply and micro-controller technology, this LED retro fit provides 200 lumens of light output (a standard 3W Oldham bulb provides 48 lumens). The beam has a 10° angle which gives an excellent spread of light, illuminating a much wider area. The hue of the light is much closer to day light, without the yellow tinge bulbs produce. It runs from battery packs giving 1.3 to 6.0V DC output with reverse battery connection protection so it will work with almost any cell combination and will provide light output when normal bulbs will not even illuminate. Installation into a cap lamp 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.

It uses 2 of the brightest LED's available - the Seoul P4. The expected lifetime of the unit is well over 20,000 hours, so bulb changing becomes a thing of the past. There are 4 modes: 1/3Watt (pilot), 1Watt (for normal activities), 1½Watt (bright) and 2Watt (very bright). Mode changing is carried out by turning the cap switch on and off quickly. Audio feedback is provided for mode changing, low battery and for over heating if used in warm environments. If over heating occurs the RETRO 2 automatically drops its power level until the unit cools and then reverts back to the original power setting.

The RETRO 2 provides full performance with 2*, 3, 4, 5 cell NiCAD / NiMHD or 2, 3, 4 cell Alkaline, 3.7V Li-Ion cells and 2.4 - 6V Lead Acid battery packs. It will also work with single cell NiCAD / NiMHD's / Alkaline batteries at reduced light output. * With new cells that do not drop below 2.3V. If used directly with a standard Oldham 4V 16Ahr battery the run times for the RETRO 2 are approximately: 1/3 Watt (pilot) - 170 Hours, 1 Watt (for normal activities) - 51 Hours, 1½ Watt (bright) - 35 Hours and 2 Watt (very bright) - 23 Hours.

The RETRO 2 is a unique LED light, which combines the proven ruggedness of the Oldham cap lamp with the latest technology surpassing any off the shelf LED lighting system.

Price £75.00, plus £5.00 UK delivery. If you would like to purchase the RETRO 2 please email me on the address shown in contact for Mike Hrybyk.
