I'm thinking of getting a custom duo upgrade to stick in an oldham cap lamp. Has anyone else used one of these?
A couple of things I need to know are
How much soldering/ wiring is involved?
Do you use the original oldham swith to change mode?
What sort of battery life can I expect?
And are there any other/ better options that aren't going to cost the earth?
Thanks guys

Tony / WelshSossy has one. I'm thinking of treating myself to one. Tony's is pretty bright!

Yeah, I noticed! But, his IS a petzl duo, whereas I want the cap lamp.conversion they do...
It seems OK for the money compared to other lamps, but a fair idea of battery life is essential!

I thought his had the upgrade? I'm sure he'll chirp up when he reads this

Are you coming tomorrow night?

batteries that are lighter than the Oldham T6 are easy enough to make. A decent charger for it (Essential with a lithium based battery) is about £20 (Imax B6 clone from ebay). I'll have my homemade packs with me at the meeting tomorrow if You want a look-see.

Err.. what's on tomorrow night? is it that access meeting? After the week I've had, access to mines is the last thing I want to talk about!

Rob, I think Tony has an upgrade too, but they make a different one to fit old miners lamps.

They also make a really bright photography lamp, but It's £90 and since I'm not going to be depending on it like a headtorch underground, I may as well have a shot at making my own!

No soldering at all.
Wiring for an Oldham cap lamp is 2 or 3 wires that need putting under existing screws in the headset.

Yes

All depends on what battery you have
and what setting you have the lamp on...

(well there may be others but you know it makes sense )

Les pretty much covers it, your best bet for a battery is to run it off 2 x 18650's but have them in a box that you can change the batteries and carry a few with you, if i ever manage to get hold of an OldHam lamp, i'll be getting one for our Jay

Thanks Les! At £55 you can't really go wrong!

I've got an Oldham head you can have, Dan. I had it in the car last Saturday but completely forgot about it after leaving the pub

If you'd given me a little bit more notice I could have picked one up for you and brought it to the Meeting tomorrow night...

are those not 3.7v each? The lamp is only rated to 6v. I was thinking of using 6v power packs for RC cars...

If you run them in parallel you still get 3.7v just a higher capacity. A 6v RC pack would be fine also.

Thanks Dylan!

I'm going for RC batteries. With a capacity of 4300mAh it should power the lamp at 200 lumens for 15 hours or at 500 lumens for 4.5 hours

any ideas where i can get a bracket from to stick this thing to my helmet?

You're better off with the caving supplies Flat bracket, the Petzl ones let an Oldham head rattle around a little, and come off far easier if You give it a knock.
