does anyone know anything about this. does anyone have one. it seems weird for dorcy to have a scuba light of any type.

Was in Super Cheap Auto yesterday and saw a couple of Dorcy flashlights there, I thought it was a brand produce some cheap plastic flashlights not expecting a scuba flashlight under its brand.:shrug:

One of my favorite lights is my little Dorcy Super 1 Watt ( single cell CR123 )...however, I have had enough Dorcy lights to appreciate them for what they are: Economical lights that are fairly dependable. There is no way I would dive with one. From the enjoyment angle, I don't dive often enough to be willing to risk not having a good time whenever I go. From the economic angle: By the time you are going on a night dive, you have spent enough on training and equipment, that it doesn't make sense to skimp on a light. And most importantly, from a safety point of view, you don't want to submerge at night without a 100% dependable light AND a backup. There are enough companies that are known for making good divelights that I wouldn't take a chance on a Dorcy, and they aren't that expensive. Check out Princeton Tech, Underwater Kinetics, Ikelight, and Pelican.

Yikes !! I just looked up the price of the Docry and its 80 bucks !!! I had just assumed it was in the $30 range....For $80 you could get a very nice primary light or even a primary and a backup.

Interesting reviews - thanks for the link

If your going to use it as a dive light may I suggest getting something a lot brighter, I have an Underwater Kinetics D8 and it just does it for me.
I am still thinking about making my own canister dive light, I hear a MR16 fits into a Maglite.....

I don't dive much but i have a tec 40 and an ikelite pca(both incans). i was just wondering about this light. I thought it might be another super 1 watt and be fantastic but oh well.

Hi I just found this thread while searching for the same above question.

I'm tired of my other 'cheap plastic' dive light breaking. I've had about 6 or 7 Princeton Tec lights break.

I've got a 1watt 45 lumen Dorcy and was wondering if the 180lumen dive light would be any good.

has anyone here actually used it?

If it's a good as the other Dorcy lights, I might buy one.

look forward to more replies....

From what I got when I originally posted this no one seems to think Dorcy is up to the standard of "real" scuba manufacturers though nobody actually has one.

I do know that my Dorcy Metal gear 3XAAA can go to forty feet and be operated. Though that is just mine.

.

appears that way... I posted over on Scuaboard also and haven't gotten any replies.

however, I don't see how the Dorcy light could be worse that the "plastic lights" that the "big name" dive like makers are selling.

I've had several of those break.

So what kind of cells does this light eat?

I think it uses 6 AAA's or 6 AA's. I can't access the other site at work that had that info. (but I think it was AAA's)

 

[mike_s]

Well I just got one of these lights in from Dorcy Direct.

I almost couldn't wait for it to get dark so I could at least test it in the backyard....
put in 6 new AAA Energizer Max batteries and headed out with a couple other lights for comparison, shooting across the backyard.
I have to say it's 3 to 4 times brighter than any of my other lights....
I'm going to try to take some pics of it compared to other dive lights and post a more detailed report in the next week or so. Also hope to take it on a night dive soon and see how that does.

But so far I'm pretty impressed.

so... more to come later..... -Mike

What lights did you compare it to? Also, could you give an evaluation of the lights waterproofing. Does it have double o-rings? does it have a secure lens? also i am assuming that the lens is plastic right?

 

[PhantomPhoton]

So what is the current draw at the tailcap?

Must not have been Pelicans...

I bought this Dorcy K2 Luxeon at Target to see what it could do:

I also have a brand new princeton tec torrent:
http://www.diveprodivegear.com/m8_view_item.html?m8:item=65409

and the Dorcy looks as bright or brighter than the Torrent which is rated at 115 lumens, also the light from the Dorcy is much whiter and cleaner.

 

[Misterbean]

I have had a UK light and a Ikelite both break in one way or another. the both still work and are diveable but it took some effort. I would love to have an aluminum dive light with a strong led but I do not know how I like this particular light.

Sorry been away from this thread for a while. apparently the "new post" email notifier isn't working.

What lights did you compare it to? Also, could you give an evaluation of the lights waterproofing. Does it have double o-rings? does it have a secure lens? also i am assuming that the lens is plastic right?

I compared it to a Princeton Tec Shockwave II. The Shockwave is a pretty bright light, but the Dorcy is a much cleaner/whiter light.

The Dorcy also appears to have a what they claim to be 80% spot and 20% flood. It's a wide flood pattern also.

Also compared it (on land) to a 3D Maglite and the PrincetonTec Tec40 (4AA), and the Dorcy 1w (45 lumen). It's brighter than all those, combined.


It does have double o-rings. I'll post some pics below in a new post. (I'll copy the posts from another thread with all the info).

So what is the current draw at the tailcap?

I don't know for sure. but somethign makes me think it might have been 6watts. (but I can't place where I read that or if I'm possibly confusing that with another light). It draw 4.8 volts though in banked batteries.

 

[mike_s]

NOTE: The next few posts are copies (cut/paste) of posts on this light that I put on another forum about dive lights. I'm re-posting it here for benefit of the readers here and for more information about it.


it's got a double O-ring.

The O-rings are pretty tight. You have to apply a small amount of pressure when screwing on the light to get the threads started. (This appears to be a good thing as it indicates a tight seal on the o-rings).

Here's a pic of it and a second closer shot of the O-rings

Here's some other pics of it in case anyone is interested.

This is the "overall shot" including the Lanyard. Most of us will likely want to replace the Lanyard with their on snapbolt/clip system.

If you want to replace the lanyard with a snapbolt on nylon line, it appears easy to do. The end cap is taped with two holes that you could use to thread them through....

Top of the Light, both off and on. (on shot from the side as it was too much glare direct on).

The batteries (6 AAA) go into a battery cartridge that is circular and then drops into the light. Four go on one side and two on the other side.

Here's all the components together....

 

[mike_s]

All.
I was tinkering with this light and a multi-meter the other night after someone asked a question about the battery configuration on the ST forum.

The light has two banks of batteries. Lets call them "Bank 1" and "Bank 2" for easy reference. (as shown on the below diagram)

Each bank has 3 AAA batteries in it and is 4.8 volts.
Then it appears that the two banks are wired in parallel to the connector that goes to bulb. (4.8 volts output from the parallel banks).

As shown on this diagram I made of previous pics

Also, you can run the light with just "one bank" of batteries (of 3 AAA's).

It has the same brightness of the LED, but the only difference is porportional reduced battery time as the light is only drawing off one bank as opposed to two banks.

Not sure why you'd want to do this on a dive if you had 6 new AAA's, unless you're a few batteries short at the dive site and still want to use it.

According to their specs at Dorcy International - Flashlights, LED Flashlights, Flashlight Batteries, Flashlight Bulbs

burn time with 6 AAA's is 8 hours. So I imagine that with only 3 AAA's you'd get 4 hours or perhaps a little less.

Just interesting tidbit is all.
