I was doing a search of caplamp suppliers the other day, mostly to see how they have come on in technology, Jeeze the price of them!!!!
OK here's a couple of makes that have changed to LED headpieces, Oldham, which sell for over 200 quid each, then you need a charger!!
The American Koehler, about the same price, but still make and sell their lead acid battery still.
There is a Canadian manufacturer and a SA maker too, but I cannot find prices on their products.
Then the cheap and nasty Chinese caplamp's which are cheap, and well, nasty...LOL

I haven't found any others, but I suppose there could still be a German company making them??? Maybe a Russian and an Indian??

Polish lamps are quite popular,and pretty well made as well,and a lot cheaper,with the batteries half the size of the old oldhams.

Oldham no longer markets a lead acid battery Jim, Koehler still have one available though, the old Oldham's were made by Oldham under license from Koehler, although Oldham eventually came up with their own headpiece design free of Koehler's patents. Not sure if CEAG the German company still makes them, but theirs were very similar to Oldham.s probably under the same license agreements with Koehler. All the new Oldhams and Koehler's are all LED and di-ion battery technology now. |

I've read on a few sites Oldham no longer market the lead acid battery, but on their site they show three models of cap lamps, two with LED heads and lead acid batteries and one with standard bulb head piece and lead acid battery...Odd, unless the site hasn't been upgraded recently??

There is a company in Canada, part of the Schauenburg Group, called Jannatec. They sell "focusable" lamps and lamps with radios inside. I believe they are at present used at Boliden Tara Mine in Eire.
There is also a South African company called Schauenburg Flexadux that market a full range of lamps. They seem to have most of the market share in South Africa. They also have them in the lamproom at Salt Union

Oldham no longer make cap lamp batteries , but a company in Swinton Greater Manchester called EnerSys (i think a USA based company) still market the Oldham Type "T" Megalight
I know this because last year i bought several boxes of them from the demolition company who were demolishing Daw Mill
They are of a clear green plastic construction anbd come already containing acid after charging them over night i left them on for 10 hours to see if they still held a charge which they did
The demolition company had about 150 boxes each containing 5 batteries , which i think they have now sold while there the lad showed me a petrol can stuffed with steel brilo type stuff with a strange smelling liquid in it
It was the Colzalene can from the lamp room which still has about 2lts of Colza in it which he gave me for nowt
The code for the batteries is Sira 02ATEX3175
and the company post code is M27 8FF
ironic that this company is based in Swinton where many of the great lamp manufacturers of the past were based

Chinese electronics are pathetic in quality, and LED lamps have a few electronic parts, their electrolytic capacitors suck! I'm lucky, I have electronics experience, so I can fault find and repair my stuff.
My computer monitor died a couple of years back, two years old!! Capacitors in the switching power supply had died due to wrong temperature ratings, plus cheap and nasty capacitors. I replaced them all with Japanese caps, perfect now.
The price of branded caplamps are a bit too high for me, I use good quality LED torches, usually Maglites. |

John:
I think you're overlooking an important issue here, the Oldham cap lamps we used were upgraded to halogen lamps which were semi directional to replace the old tungsten filament lamps which were the round ones, looking at my nearly depleted stock of spare halogen lamps it rates them at 0.5 - 0.6amps or 500-600M/a and LED's are a fraction of that power consumption, so why would large lead acid batteries be needed when a battery a fraction of that size and weight would give a longer running time with LED's.
When I converted one of my old cap lamps which I acquired when I left the industry I found (with a little experimentation) that I could get the power and range (and a better light) for a power consumption of around 80 M/a.
Unfortunately to run the lead acid down it takes days instead of hours. |

Most of the Li ion batteries now are made in China under Oldhams, Kohler etc trade names, but again I'll do a little Chinese bashing, poorer quality, they don't have the lifespan of western made Li ion batteries.
Here's the new Oldham GA cap lamp with LED head piece and their newest lead acid battery.
OldhamCaplamp
And here's their new DL16 LED headpiece and lighter Li ion battery.
DL16 Caplamp
I think there's a big price difference between the two technologies.
I'm pretty sure the use time of the LED headpiece is longer with the lead acid battery and the lifespan, average, is longer too.

That brochure is from 06/05 and has not been revised , i didn't even know Exide were still in business as a company they were taken over by Chloride Lorial years ago
i have an Exide cap lamp set with a Chloride battery dated 1976
but it is India and they only found out some years ago that they were still making Royal Enfield motorcycles in a factory set up to suppy our military many years ago , about 40 years after the company here closed

For several years now I have played with LED's and technology has moved on tremendously in the last three years and you can buy high output, low consumption LED's of good quality for less then £2 for 50 if you know where to shop; all my outside lights are now LED and driven by a small vortex generator in the stream running through my property, this powers a set of submarine batteries which I get for free as I have a contact and he gets me several when they change them on the subs and they are still in warranty.
In addition I have built LED lighting into the home as emergency lighting as we have had a lot of defective cables in recent years, they repair instead or replace and while everyone is basking in darkness we have light, we even have 2 X 12V kettles to make sure the essentials are taken care of.
LED's have lots of potential and with a little knowledge people can build their own lighting, both my 4X4's have LED lighting for everything except the headlights, these are all home made and the beauty of LED's is that you can fully waterproof them, great when blasting through 4' of water in the quarry while playing, no leaking seals and lights full of water, total reliability, and never have to replace a bulb again. Recently changes several caravans to LED lighting outside and inside, great for caravans where battery life is a concern, consumption reduced by 60% with no loss of light.
Grandkids recently built their own light tins, simple battery holder, 3 X 3mm 20,000 MCD white LED's and a reed switch mounted in the tin with the three LED's poking outside through three holes, magnet on the lid to operate the reed switch and you just turn the lid to operate; a simple project kids can build which makes them practical and introduce them to practical skills.
Converted several work lights on expedition vehicles to LED for friends, remove guts from existing lamp and replace with LED on nickel plated backing for a reflector and the diffused cover does the rest, while out off roading on expeditions they can switch the work lights on and instead of 21W or 1.75 amps (1750M/a) consumption per worklight it is now down 200 M/a per lamp, great for battery life. |
