Roy, the best protection for any lamp glass is to have it set back a fair distance from the front face of the lamp, something like the Oldham bezel arrangement.
The best anti scratch coatings are not up to sand, mud etc.

That my Scurion glass is glass I can confirm because it looks, feels and sounds like glass - I am an engineer after all!

I've got no experience of specification of glasses but I would assume that the scratch resistant coating is to strengthen the surface of a relatively ductile glass to give one that is unlikely to easily shatter but not get the surface worn quickly.
You use the same principle in metal, say for a knife, where you have a fairly ductile main structure so it doesn't shatter but harden the edge so you can maintain a cutting edge for a reasonable length of time.

Hi Roy,

How's that side project coming on? - I'm liking what you have been working on it looks very impressive!

Full stop I'm afraid mate.

It is an analogue circuit switched by small magnetic switches. The beam was by small optics, not the best by my standards. I would not be able to get anything in that I currently use and would need to assemble a custom PCB switching through MOSFETS.

It may at some time present an opportunity to test a new idea so would like to keep it on one side. Happy to refund your postage if you wish.

EDIT
For those wondering, its a kaput Stenlight.
Of further interest possibly, I will venture the opinion that a high output Stenlight would be impossible without a complete design change.

Oh well, noting ventured etc. The post was only a few squids Roy, I'm not worried about that!

You are right and I am wrong, I am obviously having a early onset senior moment. It is indeed a polycarbonate one according to the Scurion website as well.

For what it's worth, mine has remained scratch free since I upgraded the light and it has suffered a fair bit of wiping off of dig spatter so will have a been pretty well tested.
The previous one had a couple of minor ones (from catching steelwork on a dig so a bezel wouldn't have helped) that probably would have happened to glass as well.
The Scurion 'glass' certainly doesn't scratch easily but that is almost certainly the coating, there are some pretty amazing coatings that are very durable.

Its OK Nick no worries.

I had to fit a new glass, well didn't have to, to one of my roasters when a heavy roof contact took a small piece out of it. Didn't shatter or crack though.

I did manage to shatter one with a hammer deliberately though. Needed to see how strong was the stuff I was selling to people.

Polycarbonate is light and immensely strong, its the material of the old Oldham lead acid batteries. But I still prefer glass.

The best looking Oldham batteries were the black hard rubber model.

Scorpion latest

I have finally received my sample batch of front glasses after 6 weeks! Confirmed that they same as stock sample and just ordered quantity. When quantity order shipped and in transit I will submit face plate drawings to manufacturer.
All this is payed for with PayPal, if it was Capital One you would never see a Scorpion!

I have settled on three models.
A basic same as Lynx basic but uprated specs, ie IP68 - 5 metres.
An X8, same as current Lynx X2000 but with separate switching for the floods. IP68
The X12 already briefly described.

The aim is incredibly reliable and robust lamps to suit all tastes at affordable prices. However, some components more expensive that the Lynx so the Scorp will be a bit more.
I have some trial components in the pipeline for a 50 metre dive lamp, possibly later next year. There are components out there good for 10 bar (145 psi), but dear!

I use two lamps, a Scurion 1500 (helmet battery) and an RF Trigon with Belt Battery.

Last night I was out with someone who has a Trigon "equivalent". It blew the scurion well and truly out of the water. Better beam, much brighter. Hell of a thing. Very impressive.

I need to take the Trigon out more.

You will need to get your order in for the new Scorpion when announced,
You liked the Scurions crisp beam, I took this on board and now use better centre spot reflectors that give same light quality but all 2000 + lumens of it.

I am increasing water resistance to IP 68 - 5 metres with a 50 metre dive model in the pipeline. GoPro compatibility and a lot of new features.

Currently awaiting face plates.

The sign of the red scorpion will be alpha and omega of lamps. I listen to what people say and take it on board.

I have taken power as far as I want, now its intrinsic reliability and ability to withstand hard use.

Took the trigon out this evening. It's still a very good lamp.
