LED Torch

[Ian Sutherland]

Hi folks, Just looking for idea's, I'm sick of paying $13:00 or so for
a decent lantern battery. Wondering what other people think. Could buy
a rechargeable battery or pack but would expect lamp curent to be
high. (Haven't measured it, but would expect 1/2 amp or more) Thinking
along the lines of high intensity white led's & perhaps Ni/Mh cells.
Can't find the leds in Tricky Dickie's catalogue (hard copy) (will
check on-line in a few minutes).

All sensible comment's greatly appreciated.

Cheer's, Ian Sutherland.

D-cell to 6V lanton convertor, then get some 4 amp/hour D-cells all from
jaycar.

I would like to see some white LEDs used in big torches, most of the ones
produced to date are only small pocket or head type torches.

There are quite a few rechargeable bulb torhes from the likes of Jaycar.
Eveready now have a rechargeable Dolphin as well.

And then there is the battery holder you can get some places that
replaces a lantern battery with four Ds.

Have a look at the Luxeon V Portable emitter. (5 Watt white)
off about 6.5 Volts.
They have it as a basic LED and also mounted onto a star base.
Not cheap., (about USD 40), the light-output varies with
temperature and time, and you need to observe some thermal
restrictions.

Is that the electronic one that works off any voltage? The LEDs are not
that expensive.
