A friend wishes to buy an LED mining lamp for sporting AND professional use.

If it was purely for the former I would have no problems in suggesting one from Mr Fellows. HOWEVER... because of the professional angle, it will need to be ATEX approved / intrinsically safe and all that malarky.

It needs to have a good output and either come with its own charger, or be compatible with a standard Oldham unit.
He was considering one of the Oldham LED lamps Blink but output v price seems grossly out of line with current sporting lamps.
The price of a dedicated charger for one Oldham model entered the Mickey Mouse zone at the highest level.

Any good practical suggestions?

I have an Instrinsically Safe version of the Petzl Duo which I use on my "work" helmet. Its basically the same as the leisure version, except that it has plastic battery clips instead of metal and has a grub screw to prevent the bezel being unscrewed (thus preventing the circuit board being accidentally exposed in an Ex atmosphere) and is black and gray instead of the usual yellow. Came with a rechargeable battery and charger. I have added the CustomDuo upgrades to it and I find it great for what I need. Its nowhere near as bright as a Fellows but 10x better than an Oldham, and it would be just as good for uour mate's weekend exploring as well. Cost me £120 and came with all the certs and declerations etc. Use it every day with no problems.
My weekend lamp is also a Duo with the Custom upgrades.

Noting your location, there is a surplus shop in Plymouth (Knight Surplus) that advertises brand new Oldham Li-on lamps for 50 quid. He uses Ebay sometimes too.
I don't know if he has chargers but they are easy to put together and don't have to be anything fancy, unlike the lamps.
OK, these lamps are not as good as an LED lamp but at that price your mate could have two lamps, one for home and one for work and put a retro unit in the home one?

I would be careful. Adding anything aluminium will possibly negate some of the safety certification. I am not the expert on this and recommend seek advice.

I'm slightly biaised 'cos I sell Oldham lamps, but the thing with an Oldham is it just won't break down - which is what you want professionally.

Cheaper ATEX lamps look at the Petzl as Sinker mentioned, KSE lamps, and even Eveready!

I wonder if you can get things "signed off individually" as you can with many other science/engineering/risk related things.

Surely, there is a COSHH style tick box protocol and a man trained in such matters who can put a safety seal on it and give it a certificate?

I imagine that this is possible, although it is quite possible that everyone before has just used an oldham.

To the person talking about Bogey Knights in Plymouth, the Oldham MF's they had were mostly buggered. They do have some T2's from time to time though, although I have a feeling that matey has caught on to the price.

Nope, ATEX is awarded by one of a number of testing companies, there's no self certification option.

Unless you're a Chinese lamp manufacturer in which case it is awarded by photocopying the logo Laugh

This guy I think:

Not seen any listed for a while, but he had some GL16 listed at the end of last year.

I'm sure you couldn't self certificate, but surely there are firms you post your lamp to and they tick the boxes and give you the all clear, even if it is £80.

What do people do for a different piece of equipment, for instance a pH meter?

I would want the oldham to make me a cup of coffee for that price.

My eldest son went to university in Plymouth and 'discovered' Bogey knights. We have lots of things from there but luckily, he could not (at that time) transport the Admiralty pattern spare anchors home to Stoke................ IP: 109.149.102.108

Lots to look at and sort through there guys,
Thanks to all Thumb Up and I found the ATEX post of Simon's very informative. Thumbs Up

Big questions:

which ATEX rating?

ATEX isn't ATEX, there are different ratings available and you'd need the one specific for the job not just any.

(Sorry just noticed a similar question in an earlier post)

Since the level of protection partly depends on the temperature of the surfaces of the device a higher ATEX rating will in most cases get you a low output light.

Modifying lamps between the different uses may look like an option, but it's just to easy to forget certain parts or damage seals. You may just use some of your nice rechargeable batteries instead of the normal ones specified for ATEX.

I'd rather go for two lights, one for professional and for sporting use. Get a proper light for each job.

If it needs to be one for professional and sporting, get a fully sealed one and keep it like this. All in one mining lamps might be an option, but you pay a lot for a pretty low output with a terrible lightpattern and -colour. But they're fully sealed.

If you get one for each job, get a Wolf, UK or Energizer ATEX if they have the right level of protection and you should have enough spare for a good light for sporting use within the budget of an quality ATEX mining light.

Matter of fact, I wouldn't accept any other lights at a mine than the ones provided by the mine if ATEX was a requirement there. Just for the simple reason that the ones from the lamproom have a proven record and should be ok. Lamprooms aren't perfect, true, but it's unlikely that the lamps have been (heavily) modified as mentioned in an earlier post. Even if these were put back to the manufacturer's spec at home I'd still treat them as being tempered with. Even an oldfashioned OLDHAM would need a complete check as it might contain a brighter bulb, automatic fuse or seals might be damaged in some way turning it from an ATEX rated lamp into contraband.

what he said.

I'm a professional contractor and I never bother taking a lamp anywhere that requires any sort of specification. They will always provide them and in all likelihood, won't accept your one anyway.

The main exception to this is offshore platform visits, where it is near-on impossible to get provided with anything at all, and there I just take one and get it inspected by the electrician along with the rest of the gear. I usually take a maglite for this because everyone is familiar with them, although I sometimes use one of those Chinese caplamps because it's small and light with good duration.

The other exception is some kinds of civils inspections where you are going to a location with no facilities, something like a walk-through for a condition inspection of an old railway tunnel where there are not reckoned to be any ATEX issues.
