Green Light options?

[jon_slider]

I have an aluminum Tool I could put a green LED in for you. If that interests you let me know.

good to know, not ready to commit yet

thanks for the other suggestions as well, this has become a useful list of ideas

here is another one Im experimenting with.. Bought some inexpensive nail polish, put some clear tape over the lens of my Thrunite Titanium (so I can change my mind without resorting to acetone)

it is a little bit difficult to get an even coating of color, Now I have a slight clue why ladies do multiple layers.. I also have a clue why their brains seem to process info differently (the smell of nail polish, acetone, is quite mind numbing.. LOL).
4000k N219b on left, 6000k XPL on right

I think a green gel would be more consistent, and possibly rob less brightness.. Cant wait for nighttime to do more testing

next I found some green masking tape: (note both Maratacs pictured have Lumintop Tool w Nichia 219b heads)

left to right N219b, XPL w nail polish, N219b w tape:

the green tape works surprisingly well.. I think tape has a lot of potential

next I was curious on the difference between the XPL and Nichia, both with green masking tape:

The XPL works better as a source of green imo:

That xpl in the middle of the last photo looks great.

It's because it's already green without filter :devil:

thanks, I agree. IF anyone has a "real" green LED, I would be curious to see its beam in the same photo with an XP-G2

fwiw, here is the spectrum of the XPL:

and the spectrum of an N219a (spectrum images are my iPhone photos of a meter owned and operated courtesy of darksucks.com):

and for further reference, second from left is the XPL, and on far right is the N219a:

and fwiw, here is the Olight (1st on left above) i3s w XP-G2 :

and Maratac (3rd from left in the 4 beam photo) w XP-G2 :

It's because it's already green without filter

:devil:

true, but it seems the more influential variable is that the Nichia has a much larger Red component, that makes the green masking tape less effective on the Nichia than on the XPL..

I do not have any XP-G2 lights atm to compare to the XPL, but I suspect the XP-G2 w green masking tape, would produce similar results to the XPL w green masking tape..

and the budget green filter winner is: Masking Tape!
(I "wasted" $2.50 on nailpolish, before "discovering" the green masking tape.. chalk it up to R&D costs.. LOL)

one more run
3000k XPL swap in Olight i3s, 4000k N219b Lumintop Tool head, 6000k XPL in stock Thrunite Titanium

add tape

result:

I wish their were more green options. I still like my Inova X1 with green led.

Nice experiments jon, you can have some real fun with these: http://www.candlepowerforums.com/vb/showthread.php?320811-Changing-LED-Tint-With-Filters&highlight=

The Lee swatch books are not only good for creating colored beams, but also for turning cool to neutral, and removing green, pink or other unwanted tints. If you can't trap them under a bezel, cut very carefully and do a wedge fit into the front. If the front of the bezel is tapered and won't hold, try putting a drop of glass cleaner on the lens and letting that hold the filter on, I've had some on over a year that way, seems "permanent", unless I want to remove it.

I sometimes combine them with D-C Fix "sand" diffuser material to create an almost flood pattern beam. Also, artifacts are completely obliterated.

I have the Fenix with green, red, and white leds.

Cheap diy idea: buy some green cellophane filters used in video and photo work. Fit over end, zip tie in place. Cheap, and you should come quite close to desired wavelength.

Ordered, thanks for the link, very helpful

green cellophane filters

yes, good idea, I had not yet found a source.. but I should be set now
stay tuned for the sequel, entitled, "Swatch Love"

I have made many colored lights. My preferred light was a deep c8 host, an AK-A1 Nanjg 1.4A driver, and a XP-E2 emitter on a SinkPad. Unfortunately they discontinued the deep c8, but a regular c8 works ok too. If you don't want to mod., they make already built HS-802's for about $20. They are decent.

I realize the Streamlight Keymate has been mentioned above, but it was buried in a list. It really is worth a look to see if it meets your needs. Though it takes 4xLR44... there actually is a 6V single cell out there called a 4LR44, which is just a wrapped and consolidation of the same 4 button cells. I believe it will probably also work with a 10180 with more runtime and less brightness. I wonder if it will work and not get fried by a 12V A23 cell. I realize, not AAA, which is what you're looking for, not rechargeable, but it is the roughly same size as an AAA light (an AAA should half-fit, LOL). This gen Keymate came with a green LED in two models, black (part# 72003) and camo (part# 72203).

Also, Tain made some AAA Ottavino 's with colored LEDs, including aqua, which is close to green. Perhaps there was a green one, too. You'll have to search yourself, google is giving be the captcha business for some reason, and refuses to accept my non-robotness from this tablet. Tain's a really nice, collectable, etc., and not cheap.

Maybe you'd be better off having gunga do a CREE X-PE Green LED swap on your favorite AAA host and driver.

My Lee filters arrived and I started testing various colors of green they provide.

I have narrowed it down to 2 choices atm

and

the Dark Green has higher light transfer than the Primary Green, Im leaning towards Dark Green atm.. fwiw, the light on the right has an N219b, the one on the left is an XPL
here are the two beams unfiltered

next I get to figure out how to fit a gel to the XPL.. fun for me

Nice. Using proper filters definitely looks way better than your previous experiments, not just in terms of tint, but also for preserving the beam shape.

Personally, I kind of like the radioactive look of the primary green.

Technical note: the Y-value listed on those detail slips is the percent light transmission. That primary green absorbs almost 90% of your light's output. Looks like the spectra show the dark green actually letting a wider range of tones through in addition to having a slightly higher peak, explaining your observation of better light transfer, and the higher Y-value.

I've got a pack of similar filters from Rosco with the colors geared towards photographers. I think the darkest green I have is the "tough plusgreen," which is high transmission (minor color shift) puke-colored filter designed to make sunlight or camera flashes look as bad as fluorescent lights

thanks
first try fits

Happy with the tint

my new Red Eraser: (ambient light is 3000k Incandescent on red flannel sheets)

Really impressed with the Lee Filter's ability to block red so completely
