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 7.0V DC output and has reverse battery protection.
It will work with almost any battery combination and will provide light output
when normal bulbs will not even light up. 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.
The 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 NiCD / NiMH'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 tradional cap
lamp with the latest technology.
