The CSM ones if I recall correctly date back to when they were Optimac Halo, before becoming 3M Halo, before becoming Oldham Halo, before becoming defunct-Halo.

I've supplied a few bezels to the CSM a few years ago, and it's the bezels that gave more trouble than anything else, but unfortunately they are no more available anywhere.


Thats right they are Optimac, with 3M branding. Thats not so good, I guess when the batteries give up the ghost they will be changing back to Oldham then!

Are they H1 (yellow) or H2 (orange)? Have quite a few new old stock H2 batteries Innocent

That's them, unfortunately those were out of manufacture ages ago, I got rid of the last I could source back in 2013.

Pity anyone who needs a lamp, especially quantity.

Miners lamps you cant batteries for after a few years, a supplier who as stopped taking orders, (for a short time though) or hideously expensive 'Gucci" lamps.

Maybe the guy who still uses an Oldhan lead acid has a point after all

A good miner will break anything given to him. Wink

When I was in charge of a lamproom in the UK we got at least one Oldham "G" with per week that didn't survive being run over by a vehicle, sometimes even more. So much for Oldhams being industructible. KSEs don't need to be run over. They have got other weak spots that will break purely by using the lamp, same with DULA cordless lamps.
Wisdom KLs seem to be good quality, but I have no experience how they cope with a working mine. But I will test my two KL8s at work. They certainly cope fine with mine exploration.

Miners like to stick with their traditional equipment. It's hard to intruce something new. Here are some of the arguments I got against cordless lamps when I tried to introduce them to a UK mine in 2007:

-too light
-not bright enough
-too small to handle
-helmet will get lost if not attached to cable
-feels unsafe without a cable
-selfrescuer is not counterbalanced by battery
-no glas, not suitable for welding
-too easy to take off site

The only true one at the time for some of the lamps:
-charging arrangement not suitable for mining environment.

Same arguments will apply to helmet-mounted batteries.

For me, I Iike a lamp attached to a cable, so that if my lid falls off it's less likely to run away. IP: 80.177.163.61

Its a matter of numbers, if you have 200 guys working underground then one failed lamp per week isnt bad

Does not surprise me in the slightest with ex NCB/British Coal management.

The KL8 is the nearest you can get to a modern version of the design, I have one and the main difference with the Oldham LED caplamp is the lack of focussing reflector arrangement in the lamp head.

I dont do lamps with belt mount except for one super roaster, the most popular as I have said has a battery that weighs only 165 grams but lamp buns on for up to 24 hours. It would be kind of silly to have a cable bigger and heavier than the battery.

I have heard of people taking a fall and their chinstrap breaking, but helmet never far away. If it went down a shaft I fancy the wearer would be following it.

We had a total of 240 lamps. One per week was just the average number of run over lamps. There were a lot more repairs of other minor damages. IP: 109.47.3.31

I have just been looking at the range of lamps and have to say that I am impressed. I note that they use genuine Sanyo cells so you know you are not getting junk batteries. This is a major point.
The prices look keen as well.

On face of it, if anyone wants this type of lamp I would say they represent the best buy at this time.

Roy I never thought you could endorse any other lamp!
Are you going to try one yourself?
Certainly if I had not put so much cash into the new Oldhams I would be thinking of them myself, especially since Simon R must be impressed as well.
I switched from the lead acid Oldhams around 12 years ago, and at that time went down the Speleotechnix route.
Using helmet carrying lithium ion batteries.
I must say it always seemed to me that the helmet carried too much weight, and when a serious accident a couple of years later wiped out this technology for me I returned to the Oldham fold, once more.
To those contributors who think that this thread has gone on a bit.
I will make just one point, underground only two things matter, your lamp and your mate! The latter should not be discussed in a forum like this but we will debate the former for some considerable time.
