    Help: Adapting new power source for old Vistalite head light (Lightstick)

    Greetings:
    New years brings clean up around the bench and i found these 4-5 old Vistalite headshells that I inherited that are collecting dust. They were powered by a lightstick, but the run time was ugh and eventually it stopped charging or giving power or wire was bad or all three.

    I have lamps that are rated 5,10, and 15 watts.

    I used a couple clippies and attached it to a 4xAA back up bundle for my Dinotte and the lamps worked fine. I had hacked into the cable to bare wire to make it work.

    Question: Can anyone suggest an easy power mod so I could mount one of these as a back up flood light source on the commuter? A Batteries Plus ready to go product? The original cable had one of those female plugs, but I can solder and mod.



    thanks!

    How about one of these 6v battery packs:



    It should a little less than an hour with all three lights running. You can solder the wires from the old pack to it and zip-tie/velcro it underneath the stem?

    I used to have a Nightstick set too! Nice design, but run time was not very good.

    You have a primary light (Dinotte) and plan to use this as a backup only? How about a Y-cord to the Dinotte battery pack? Or are you planning on running the lights simultaneously?

    If you want a separate power source, go for a nominally 7.2V battery. Overvolting the halogen by about 20% is a good trade off between more light and burning out the bulb prematurely. The original Nightstick battery provides 7.2V IIRC, for the same reason.

    To err is human. To moo is bovine.

    Who is this General Failure anyway, and why is he reading my drive?

    Ah yes, over-driving halogens gives higher-efficiency. If you increase voltage by +20%, you actually get even more light, like +25% more lumens. In that regard, you can get a pre-made battery-pack and not have to worry about mounting them:

    That might do the trick.
    Guess I'd have to go for the charger too (I have the old Vistalite charging brick but not sure about the connection.)

    You have a primary light (Dinotte) and plan to use this as a backup only? How about a Y-cord to the Dinotte battery pack? Or are you planning on running the lights simultaneously?
    I commute on and off commuter paths in town, and there is a lot of ambient light except on a stretch of path through a residential area. At that point I crank on the flood light for the path. So I wouldn't be running the lights at the same time. Mostly I have these several VistaLite light shells and bulbs and such that they are just not being used so looking to use them somehow,
