View Full Version : Lighting Question: Hooking up a Lumotec to a battery pack

Hey all,

I was just wondering if anyone could forsee any difficulties with connecting a Lumotec Oval Plus fork crown mounted headlight to a pack of 4 AA batteries?

The way I see it, its a 6V light, so 4 AAs at 1.5V each should be right? Has anyone done this before or seen it done before?

It would be a temporary measure before getting a wheel built up with a hub generator at a later date.

Thanks.

Daniel

This is OK as far as I know. I've done this to test Ovalplus lights in the past. Be aware the capacitor that powers the LED will likely sap a little bit out of the battery capacity (but not much, I imagine).

If it had been an E6 then definitely no... the power surge plays absolute havoc with the magnetic reed switch. The Ovalplus switch, if it has one, is straightforward electrical switch.

Thanks for the advice, Rowan.

I have wired a Basta 6V/2,4W generator light like this and used it for several months now. I'm using rechargeable AAs with 1,2V nominal voltage, so I have 6 of them. The battery package delivers more than the recommended +20% overvolting when freshly charged, but so far the bulb has taken it OK. The Oval Plus standlight feature shouldn't be a huge issue.
