What is your budget? If I were you I'd possibly do what nem did and get Greg to mod an old DR can light or just bite the bullet and get one of the can light combos that me and Greg do...

You are very welcome to try out Selinas can light this week on a night dive. It has three brightness settings and a very long burn of about 4-5 on high and over 40 on low.. But be warned after trying it, all other lights will make you the "prince of darkness"!!

You won't get similar for twice the price..

Ignoring the DIY options, which basically I know nothing about, the SOLUS products certainly seem to fit the bill:

You'd be looking at approx 1/3 of that price Pete..

Well you always talk about "Fit for purpose" and realistically for you "Fit for purpose" you need to think about a Cannister Light,the possibilities and options that they have and the aplications that you can use them in are very broad in their spectrum.

For example with a Can-light during entry and exit from the dive site you can use one of your double enders to clip her to your top "D-ring" from the base of the light head so the beam faces downwards,this frees up both hands for (catchbag,camera,dive flag,fins...whatever) in this position its not in your dive buddys eyes or attracting UFO's its illuminating your way and others way to the dive site.

This can also be very useful under water when deploying an SMB or taking a photograph where you dont want too much light to flood the area,just clip her off and you have both hands completely free (and again as its pointing down nobody gets an eye full),and with a Goodman style handle I would say you can still take a good photo with the handle actually on and then point beam an area for a pic or illuminate it from the side like I have seen you do many times before.

Also when clipped away its in its upright position its very flush to the body which helps with streamining and avoiding any entangelment in various environments as the light cord when dealt with properly will be tucked neatly into the waist band of your B/P,deployment is also easy as its one clip off and you are away.

The large torches like the D8 have a very sizeable head and for the actual light output vs size I dont think they are "Fit for purpose" with a can-light the bulk of the torch is on your waist and the light head is small with IMO a superior output and with a decent can-light the burn time is exellent,in wrecks you will never see serious divers with much other than a Can-light and for serious Night diving I think the Can-Lights like mine and Binks have more than proved their worth.
(and now with the beam intensity adjustment they have just added another facet to their credit).

Just one mans opinion though...

(This is just one example)

Could well be. I haven't looked at their site for a while, but the products are very good.

I have seen a Solus light before. Built like a brick shit house. But the light beam was really horrible and spread out.
I almost fell over when I found out how much it cost.

I have a couple of UK eled back up torches that are really good, not as good as the IST back ups you have seen that I use but still very adequate as back ups.. They will be up for sale soon..

Hi Pete,
I've just got a can light from Greg/Rob. It's a little different from Robs. His has 4 x 3W LEDs which a re very tightly focused. My one has 3 x 3W and 1 x 10W LED's. So all up 19W of LED power 8) The 3W lights are tightly focused and the 10W is wider which gives a lot of spill. I'm very happy with it. You'll see it during tomorrow nights dive. It's got three settings too for brightness and power consumption. On full power it burns for between 2-3 hours, which is much less than binks, but I figured I'll not be diving many places where I can't recharge at the end of the day.

As for the backups, again the modified IST torches that Greg is doing are fantastic. There are two types, the one you've seen with bink with the tight square beam, and another one that has a slightly softer focus, producing a more rounded an slightly wider beam. I've got one of each, but would probably recommend the wider.

I think you gotta try out the different options to. You are more than welcome to try all my torches to see what you think.

I've been meaning to take some photos of my light, and compare against others and post them. I'll get around to it eventually.

There's a difference between those first two, Pete, that is not just about brightness. You need to think about beam angle as well. The more time I spend buried inside wrecks and caverns, the more I'm really appreciating a tighter beam angle. But then night diving, I prefer a wider spread.

Of course, you're preferences may be different. But it sounds to me that you might find a focusable light more use than a dimmable light.

With my 10W HID, Pete, the intensity of the light is much less when it's not focused into a tight beam. I'm not geeky enough to really know what I'm talking about, but the whole watts, lumens and luminous flux arguments are worth thinking about.

The perceived intensity of the light is basically the amount of light it throws out divided by the area it falls over. So even though a 10W light is pumping out the same amount of light, how some underwater beastie reacts to it will depend on the focus.

My guess is that you're looking for an unobtainable product here? Between wreck and night diving, you'll probably want control over focus. For night and "friendly night" you're wanting dimmable. I'm not aware of (m)any dimmable, focusable lights out there.

There are lots of focusable HIDs, lots of dimmable LEDs... and a few focusable LEDs.

Yeah, it's definitely worth checking out individual lights when you can - plus also the specs of various lights.

Ignoring the price issue, some commercial lights you might want to check out:

Greenforce make some very solid lights, some nice features on some models - www.green-force.com
Diverite lights are ok, but none are dimmable - http://www.divegearexpress.com/lights/
Halcyon lights are nicely put together, but only make HID - http://www.halcyon.net/?q=lights
Men of Diving sell a focusable LED - http://www.men-of-diving.com/

Almost all of these, apart from some of the GF and DR lights are probably going to be out of your price range - but you will get an idea of different features that you might want to aim for.

Pete wrote:.....The second thing, that I see nothing of here is there is no recommendations on the backup torches. Now I really like those small intovas (I have seen the same torch branded tusa and cheaper too), but what I dont like is the cost of batteries!!! Im talking about those small ones that take two batteries and have no handle so they can be stowed easily.


The question is what is it you require from a back up?
If you dive in cave systems you need one that can get you out. Same for a wreck.

Night diving is similar. If your primary fails you need one that will get you back to the boat/shore. They dont need to be all that bright. Just super reliable with enough run time to do the job at hand and some in reserve.

BUT you could also define a back up as a light to use as a primary for when your primary is lost/stolen/getting charged/left at home. In this case something brighter may be needed.
Size is also important. It shouldnt be so big that its a pain to carry or so small that its batteries are small and it has to short a run time.

The new Intova narrow beam is a good little light. I hear you can use CR123 rechargeable in it which you can get really cheap online. Infact you can get 2 cells and a charger for cheaper than what most dive shops want for a pair of non rechargeable cells.
But burn time isnt all that long and they will dim down as the cells go flat. Also dont believe the hype of it being 4.7watt. It isnt.
There is also a new UK light that uses a Cree LED and a Li Ion rechargeable cell. Looks like a good light but output is limited to reduce the heat in a plastic bodied torch.

My favorite at the mo is the Ultrafire W200. Highly modified of course. Ask Bink about them. He now has 2.

If it's anything remotely more than a quick poke of the head in a passage, two would not be a bad idea.

I'm not a fan of rechargeables in a backup. I've not found a rechargeable battery that doesn't lose some (if not all) charge over time. Not a pleasant feeling to pull out your backup that is just a vague glow.
