Advice need from gurus regarding green LEDs

I have been putting lights together for night hunting, usually a P60 host, single mode drop-in, remote pressure switch and the DX 28mm aspherical lens.

I was asked recently to assemble one with a green LED. Apparently if is for somebody that is visually imapired. My first thought was should visually impaired people be going out at night with guns! I have been reassured it is not a serious impairment and he can see much better at night with green light.

I know there are a number of green LED drop-ins available and I know the output will be significantly less than with a white R2 but has anybody any experience of them before I waste his money? I would like to be able to illumnate a rabbit at 50 metres which I think should be achievable with the 28mm aspherical lens.

A green XP-E is always an option, and it is as bright as their white equivalents. There are green Cree XR LEDs also, if you are intent on using aspheric optics.

Thank you, I thought that coloured LEDs tended to have a lower output than white ones.

Can you recommend any budget suppliers of either green XP-E or XR LEDs or drop ins?

No, Green and Blue LEDs will actually be putting out more power than a white LED as there is quite a bit of loss in the phosphor that makes a blue LED white.

Would a green diffusor work?

I was hoping someone would order this one from Manafont and test it before I got one to try. It appears to be an XPE.

Sorry to steer a bit off-topic, but does anyone knows any place that sells blue SST-90 (on a star)?

I think you mean XR-E, XP series components don’t have the metal ring on them.

Not exactly budget but its green... http://www.luxeonstar.com/Green-530nm-20mm-Star-LED-161-lm-p/mr-m0100-20s.htm

Not really. Filters cannot produce light in wavelengths the LED doesn't so filtering a white LED will drastically lower the output. You are much better off to use an emitter of the appropriate wavelength than to filter a white emitter if you are really trying to get the most out of it. I played some with Red emitters vs filters and the difference is huge.

I ordered a couple of the greenies from Manafont. One is going in a direct drive aspherical gun light, I will update when they get here.

First post here ever (super newb) but have been reading alot just registered couple of days ago.

I have this green drop-in, it is pretty bright and the price was good also single mode. It has OP reflector. I ordered the camo 501b body to put it in. Ordered aspherical lens from DX to use with it to see how it works(DX seems alot slower then MF). Going to attach it to a bow and use a pressure switch to activate (North East Texas Hog Hunting).

Welcome to BLF.

That drop in looks pretty cool. Any chance you can take a beam shot of it?

I would be interested in some beamshots too!

Really want to get myself green and/or red flashlight!

Thank you,

The only device i have to take pictures with is my iphone. Will try and take some this weekend and see how they look.

It has a nice bright hotspot and nice spill. I am figuring with a lens swap it might tighten it all up and become a very usable gun/bow setup. I have used it in the alley behind the house with factory lens and it is nice should be good for 50 yards maybe 75 as it is right now. Wish they had a green led that was more powerful. Have seen on ebay some drop-in's that say they are Q4's but are more expensive. Think you can get a green and red one for around $20 maybe.

My first led flashlight was a christmas gift from a couple of years ago a Coast Led Lenser 110 lumens that is focusable. He shot a raccoon at bout 120 yards but the only thing he could see was body mass not much else. Now i own an XML 502B and 2 sipik zoomies using 14500 flames (wow!!!! blows the coast light away in zoom mode and flood).

I have this drop-in and have posted on it here before. To recap:

  • Not bright
  • Not emitter pictured - 2 elements and 2 bond wires vs the 3 element/4 bond wire pictured
  • Only driven at ~600mA at tailcap IIRC

MF has a second green P60 drop in that it a little more expensive here...

...but I haven't bothered to order this one to see how it compares. As mentioned earlier, MF has the green emitter only...

http://www.manafont.com/product_info.php/generic-cree-green-beam-led-flashlight-emitter-p-9099

...but this and a new driver to upgrade the generic drop-in would cost as much as the more expensive drop-in already packaged.

And welcome to another North-East Texan to the site! What's your general location? NE-Texas covers a large area... I'm Longview/Henderson area...

I have two DX 501b with XRE greens (Ad says luxeon K2 but came with Crees). First thing was to change to a single mode 1400ma AMC7135 driver for most lumen. Original driver is weak. Have one mounted on my crossbow with the original SMO reflector and it's good for 50+ yds. Used an aspherical DX (caution all my latest aspheric lenses from DX,KD,lightake,wellparts....SUCK!) on the one mounted on my Saiga 500 s&w semiauto conversion. Good to 100+yds. I'm going red now. https://budgetlightforum.com/t/-/7273

Off to hunt Turkey, season starts tomorrow!

Keltex78 - i live in the dfw area but we hunt in red river county real close to the red river. Havent really looked at the emitter to see what it looks like. We setup a bow shot about 30 yards hopefully it will be bright enuff to get that done if not we also have an led light that we built on a dusk to dawn sensor that will help out.
Since flashlights have become my recent obsesion i will keep trying new stuff to find a green light that works that is in my budget. :slight_smile: searching for budget lights to hunt with is how i found BLF and this site is what i am all about quality + budget friendly + diy!!!
:bigsmile:

The tree in the pics is about 10 yards and the mailbox is about 22 yards. The green led is in a old school camo 501b with the cheap green drop-in running on an 18650 red and white ultrafire, measured tail current was 590ma (both from MF). The other pics are from an ebay sipik clone citi power branded running on a 14500 flame in the extended position.
