Dorcy Cool GREEN (Bulb Retrofit) -- Picture Link

[**DONOTDELETE**]

I finally got the aqua green 4-led bulb in the mail, and I immediately put it in my 4D MagLite. It was nice and bright all right, but I realized that since it is driven off any 4 x 1.5-volt battery source, I popped it into my Dorcy Cool Blue (about $7 and change from Wally World), and *SHAZAM*, it became a quite bright little flashlight, even outshining the TEN white-led arrangement in my LightWave 4000. Here is the link to a digital beamshot picture I took: http://communities.msn.com/e5qmoda/shoebox.msnw?action=ShowPhoto&PhotoID=93

(but at $20 + shipping, this 4-led bulb cost about three times the Dorcy flashlight)...

Holy cow, Mr Bulk! If that's a LW4K you're pitting it against, that's one heck of a lot of green light! Wonder how it'll fare against the infamous green Arc LS that no one's ever seen...

Hey Mr.Bulk any chance of posting a pic of just the bulb out of the light?

 

[Gandalf]

That's really bright! You said that it's the an *aqua* green 4 LED lamp? It looks about the same color as my green Infinity; pretty much an emerald green color. Is this just color distortion in your picture, or does it
have very little blue in it?

Also, where did you purchase the 4 LED bulb replacement? I've only seen 2 & 3 LED replacement bulbs, so far. TIA.

According to bulb supplier John Bechtold (found his name at least) these green nichia's are something like 11,600 mcd each, so times 4 that would make it 46,400 mcd. I think the WHITE Arc-LS is already in teh 100,000 mcd range according to Craig at the LED Museum. But that aqua green spectrum coming from the 4-led bulb sure seems bright to my eyes.

Ryan,

Yeah I need to get it apart and get my camera charged, then I'll put it up.

Gandalf,

The pic shows a pretty accurate rendition of the color, to my eyes at least. Did not see much blue in it. The guy's name is John Bechtold, he's on e-bay selling the multi-led bulb retorfits. The 4-led one I had to ask him to make, he said that's the max he could go, spacewise, on a flange-type bulb base.

MR Bulk?. What is his ebay name or can you post a link?

Will the Dorcy 4-AA metal flashlight work with the PR bulb too?

Well, that's the battery config. in my Cool Blue and it works perfectly, so I would say yes, it should.

I just received my order of 3 @ 4 6400 white LED bulbs from John. In a PT40 with a dummy and three lithiums it has a tighter and brighter hotspot than my LW 2000 with three lithiums and a slightly looser and dimmer hotspot than my Inova X5.

John specced my lights at 40 mA per LED with 3 new alkalines and 48 mA per LED with 3 lithium LED's. John will individually tweak your bulbs to the input voltage with which you intend to drive it.

I'm satisfied with my purchase.

Hello Fellow Flash-a-holics,

This is John.

I built MrBulk's lamp with 4 Nichia Green 11,600 mcd LEDs. Of course, they produce more than that at 40ma per LED. He had a special application wanting to use 3X alkalineand lithium or 4X NiMh with the same bulb.

I do custom work, as stated by other members. I have Aqua, Blue, Green, Amber, Red and White LEDs available.

Just let me know if you would like something built.

Thank you!

John

Yes, they should interchange. I stole the PR base LED from my Dorcy cool blue and stuck it in my 4D maglight.. Then put the incandecent bulb in the Dorcy and tossed it in my toolbox for short emergencies.

The LED in the Maglight is now focusable and while not super bright should have a runtime measured in WEEKS.

I did the same thing - that's what gave me the idea to have John build me the green bulb...

...just FYI, check out LEDtronics.com...they also have PR based LED bulbs. They come in 3V, 4.5V, 6V and in 1, 2, 3 and I THINK a 4 LED cluster. I got a 3 LED cluster (aqua green) and put it in a Dorcy Boss 4AA flashlight (same size as a Cool Blue, but it's black, fully rubber coated, and only $3.97 at Dollar General...

), and it's the second brightest LED flashlight I own... just slightly dimmer than my X5. The X5's hotspot is much better, but in total light output, they're pretty close...

...there is nothing in the world more frustrating than a lousy beam...

 

[EMPOWERTORCH]

How much for a 4cell 4 LED cyan bulb with PR Base?

 

[**DONOTDELETE**]

John charges me $24 shipped for the 4-cluster. But this time I'm getting it in white, and I asked for it to be overdriven at like 60ma -- damn the torpedos, full speed ahead! Will post beam pics when I get it...

I bought a white 3 LED lamp from John & am very happy with it. His work can only be described as very professinoal. He told me at one time he went to med school to be a surgon, but changed his mind. His work on his lamps reflect this type of precission skill. TX
