I just replaced the CR2032 in my green Photon with 2 CR2016s. Much brighter.

Still the turquoise is brighter and easier to see by, IMHO.

So, I would give the edge to the Turq in brightness?

Which has the better battery consumtion?

Any other thoughts on the turq vs green?

Thanks!

The reason I have the green is for the 7 day burn time. The turquoise because it is the brightest. A super green would be just interesting at this point. I need a narrow beam white, to me it seems to be a bit brighter than the turq. Now if the super green will burn for 7 days, then I will convert mine. Has anyone tested it yet??

Well of course I've tested it!

Plus here's some other stats on comparable lights:

The Turquoise gets about 12 hours of light from two CR-2016's. The Green gets 7 days from one CR-2032. The Super-Green gets about 20 hours from 2 CR-2016's.

The Infinity Task Light (white was tested) gets about 40 hours from one AA alkaline battery, but is not as bright as a new-batteried White Photon.

The Streamlight Stylus (3 battery model, White again) gets about 12 hours from 3 AAAA alkaline batteries, and burns BRIGHTER than a White Photon with new Batteries, plus the case, not just the LED is waterPROOF. You sacrifice size, however, by clocking in at 6.5625" long, which makes it slightly unwieldy to go in a shirt pocket next to a pen, but not for a jacket pocket. Works great for poking into the innards of a computer, plus you can use the LED bulb itself to push/insert/move things around as it's non-conductive (the metal barrel is NOT).

Just some idle musings...

Thanks for all the great info, Tim!

Anyone else out there really like the blue Photon? I think the supergreen and turq are more useful, but the blue is just cool...

Here's another confirmation the turquoise is a bit brighter than the green. Since the turquoise is also whiter than the green, it's the brighter light all around. The turquoise is definitely my fave photon, by far.

After I had explained to my daughter about the various wavelengths of light that Photons use, and the relative merits of them (chromatic aberration, Perkunjie shift under scotopic conditions), she put it in perspective:

She said, 'if you are getting a Photon for a woman, get turquoise; if you don't have turquoise, give her blue.' I asked her why, since the science would tend to suggest other colors as being more useful. She explained, 'it's a girl thing, dad.'

After using literally hundreds of the things, I have settled on the narrow angle white as the best all around light. It gives you true colors, which is sometimes very important (vision of Jim March trying to splice color coded wires using a green Photon springs to mind
smile.gif
).

Red is second best. No chromatic aberration (although the new white has a lot less than did the old white), excellent run time.

Blue and turquoise are good for marking at night. There is very little natural blue light at night. Of course, some men (Joe Talmadge comes to mind) like turquoise as well.

As far as I know, no one has ever said that Joe is a 'cowboy who rides side saddle.' as we say in the West.

So, if you like turqoise, go for it.

Sorry I didn't respond to this earlier, but I was out all day getting my legs waxed. But seriously, turquoise is for real men!
It's very bright, and close enough to white for any of my uses. I actually haven't tried narrow-beam white, however.

 
Joe; since you are so narrow-minded (
smile.gif
), I may as well send you a narrow beam white Photon. I have a bunch, as I just equipped my son's Cub Scout pack with them.

Need any Carley lamps in addition??

Walt
 
Walter Welch, the candyman of bladeforums! Well, don't wanna be greedy, but as long as you're asking
smile.gif
If you've got Carley Lamps for 6 C-cell flashlights, that'd be perfect. I had actually planned to order a few in your next order. Actually, now that I think about it, I have that 7 AA-cell Brute sitting at home, with what may be nothing but a burned-out bulb. Any of the Carley lamps able to handle 7 AA cells? Thanks!

Joe
 
I checked the narrow beam white(I gave away a bunch for christmas last year) against my turquoise. In a dark room, crossed the beams, and to me the white seemed brighter. So now its on my list to get. I like the ability to know the colors I'm looking at. When I finally get one I'll probably move my turquoise to my backpack, or my car. No telling.
Also on my list of lights to buy is a PAL gold in white. I picked up a regular PAL light a few weeks ago, and I like it. The constant on feature makes it easy to find in the middle of the night. Need a few more, one for the car, each bathroom, and maybe one for the kitchen.

Joe; Carley does make a PR base xenon lamp for seven C or D cells. Of course, you could use it with AA cells, providing you changed them fairly often. Like every couple of hours or so.
smile.gif


It would be bright, however. 14 spherical candle power, over 3 times brighter than a 3 cell xenon lamp. Assuming that the AA cells could maintain operating voltage.

Walt
 
What's Spherical Candle Power?

Imagine a bulb mounted in a reflector. The total amount of light generated by the filament is called the luminous flux of the lamp and it is measured in lumens.
The reflector then takes that light and aims it in a particular direction. The intensity of light illuminating a surface in front of that lamp is quoted in candlepower. Of course, if you moved the bulb further away from the surface less light would hit it, so the candlepower will fall even though total lumens are the same. So you see they really are separate units, one measures total light output, the other refers to light in a particular area.

Particularly for reflector bulbs the light is often quoted in peak candlepower, this is the maximum candlepower one metre in front of the lamp at the centre of the beam; or it's the distance at which the beam is the most intense and focused. Whether the flashlight company has kept to the 1 metre standard or not is usually known only to themselves.

In the USA the matter is confused because some quote the total light output in units called "Mean Spherical Candle Power" or MSCP. You can think of this as the total candle power radiated in all directions, a measure of total output and hence measuring the same thing as lumens. To can convert from MSCP to lumens you have to multiply by 12.57 (12.57 = 4pi = the surface area of a sphere)

Of course there is no conversion to go from raw candlepower to lumens. If the MSCP is not specifically given, then there is no point in converting the candle power value.

In the case of 14 MSCP = ~176 lumens.
This is roughly 2 MSCP less then what a SureFire P91 (200 Lumens) 9V lamp is quoted as.
So a SureFire D3 Guardian is according to Walt Welch, well over 3 times brighter than a 3 cell xenon lamp...

This is only if all the figures are reasonable accurate!

Joe: Is that Carley for a 6C Maglite? If so, what do you think of the C lights vs the D lights? Personally, I always thought he C's would be more useful if they didn't have the same size head as the D cell model. A smaller profile (kinda like your Brute).

Yah, I agree, the overall low profile of the Brute was nice. What I like about the C cell Maglites over the D cell Maglites is that the barrel is much thinner. The only time I carry these big lights is if I need lots of light PLUS a backup impact weapon for defense use -- if I merely need lots of light, I carry a Surefire or UKE 2L. As an impact weapon, the barrel of the D Maglites is way way too thick for me to handle. The C Maglites are much closer to what would be my idea. The Brute was perfect!
 
Gotcha, Joe. Too bad you can't just carry an ASP in Kalifornia.

If you were looking for a rechargeable to fit that "possible weapon" bill, the Super Stinger might be a good choice.

Here is a good reference for how light is measured and conversion tables between different systems: http://www.intl-light.com/handbook/ch07.html

Unfortunately, there is sometimes a rather poor correlation between theoretical data and real life observations.

Carley's data state that the KSR lamp is brighter than the Xenon Star lamp. Well, when I actually compared them, I found this not to be the case.

Some Sure-Fire lights put out a lot of light, but unfortunately it is not well focused for distance applications. Thus your ability to resolve objects at a distance may be better with a MagLight, even though it is producing a lot less (total) light than the Sure-Fire.

Walt
 
Walt, could the reason that your ability to resolve objects at a distance may be better with a MagLight, even though it is producing a lot less (total) light than the Sure-Fire, be that the reflector diameter of the SureFires are much smaller than a MagLite?

It seems logical that a bigger reflector should be able to project further. My experience with the SureFire 12PM is that a 6D cell MagLite beam is totally out-classed.
 
15s; it is more a matter of quality rather than quantity. The Sure-Fire reflector is a pseudo Fresnel reflector, which usually can't even reflect a circular beam; it is most often elliptical. The MagLight has a well made parabolic reflector that casts a nice circular cross section beam. Walt
 
Walt,
I'd be interested to know which flashlights you are using to make this comparison. I'd like to think you are using a 2AA MagLite with whatever sort of super lamp in it and comparing it to something like a SureFire 6P with standard lamp module. These both have roughly the same diameter lens.
Comparing a 6P to a 6D cell MagLite would certainly allow the MagLite to produce a tighter beam and project further which is something a standard SureFire is not designed to do. It’s designed as a close combat light, either weapon mounted or for use with a hand gun at short range.

A better comparison would be a 6P with TurboHead and a 6D cell MagLite...

All the MagLites (even those I've seen with super lamps) have had a poor quality focused beam, with spots and rings. I have never seen (or heard of) a MagLite with a perfectly circular beam of pure white light. My 12PM (which has a 2.5" lens) produces as near a circular beam as you could want/need. I'd rather have a flashlight with an elliptical beam of pure white light, than a MagLite.

I used to think that MagLites were the Dog's proverbials. Now I'd use a Pelican StealthLite over my 5D cell. I don't like having to refocus it everytime. On/Off - simple; easy; effective; reliable.

No hard feelings

P.S.
It would help me if you can clarify this! And where can I get one of these MagLites you speak of cos it'd save me a fortune in Batteries!!
