Lambda lights key lights

How many people are using these? I think I have seven or 8 of these and they are on about every key ring. I would say green is by far the brightest. But I have the greens blues and one pink. Even the ones rated for 1 year on a set of batteries are going on year 2. It will be good to see how the regulated 3 year ones will do. So anybody else have these? http://www.lambdalights.com/keylight.html

I’ve been looking at those for ages but have never been quite tempted enough to get some. You may just have encouraged me enough to get some.

What is the pink like? Is it clear lens and pink LED?

They’re all clear lenses – they are made from Maglite bulb holders.

Thanks, Don! :bigsmile:

They do look quite nice but I already have tritium vials which are really bright and don’t require batteries.

All of these are brighter (but bigger) than tritium vials

If you get a green you can see in the dark with it. I have a bunch of pics I can post but they are quite good for finding your keys in the dark or putting on the pull cord for a ceiling fan. I will find some pics.

These are quite a bit brighter than any H-3 that I have seen. I have some that are still on the first 2 button cells from going on 2 years. Here are some of the pics.

And outside Light is on tree branch about 20 yards off my front porch.

wait so the green one glows in the dark or something? that is actually a neat idea for the ceiling fan pull cord. i am always just pulling the air trying to find the cord.

or are you saying to keep the light on 24/7? wouldnt the green light be too bright then?

These are wicked cool, I’ll have to get one of those regulated 3-year ones :bigsmile:
I appreciate the heads-up on these, lawallac. Very cool.

Lambda made them because he had a lot of Mag bulb holders lying around from all those Varapowers he’s sold.

Go for it!

Thanks for the pics, lawallac. The nano is looking more appealing to me, seeing them side by side.

The light does have a small hole that is filled with GID epoxy. I think Green has green glow and Blue has blue. I actually have the one pink that has Pink GID, but I think it was the only one at the time. But yeah the light are shipped to you turned on and glowing. I know it’s weird going out to the mailbox and you may find a glowing envelope.

I tried using them on the dogs but my animals are a bit rough and knocked the lens off one of them. He has since changed the design from a glued lens to a press fit one and i haven’t had a mishap since. I took them off the dogs because they were too bright IMO, and I thought they probably bothered them. But it was cool being able to identify them in the dark, color coding them.

I would highly recommend something other than green for a fan pull unless you are looking for a nightlight because it will light up your room to dark adjusted eye. Blue is second brightest to the eyes, but it’s hardest for the eyes to focus on. But red is probably the easiest on the eyes. He usually has extra batteries you can buy, but these run years just on the 2 that come installed.

Blue and green are most efficient.

The end of this yr will be 2 yrs running 24/7. These are really super efficient LEDs at these low current, like 20uA. The 3 year ones use the most efficient LEDs but may not be quite I bright, not sure if you can tell. I didn’t buy one of those since I already have so many. But it’s been kinda quiet at the FNF and people there already know how nice these are.

wow that just makes the cool factor move up a notch. i seriously didnt think you were gonna say yes , turned on for 2 years straight. thats unbelievable. and it doesnt get hot in your pockets or the light itself?

yea it has been pretty quiet at fnf. lamda hasnt posted anything new for a while. i always check back for updates for the vpt’s.

Shouldn’t be hard. The internal resistance of the cells should limit current nicely. Which is why Fauxtons work for more than a few milliseconds.

Get the highest efficiency 5mm LEDs you can. You should only need a few tens of microamps current to drive the good ones. Blues are probably the most efficient. But the human visual peak is in the yellow-green area. So those will give more perceived output for a given current and efficiency.

Just make sure you don’t short the cells in the container. Insulation is your friend Smile

If the rating on these is remotely honest – which I doubt – they should be fun. Not that you’ll get a year out of these.

Years ago I bought a dirt cheap bag of assorted LEDs – including the world’s dimmest green LED – your typical keyboard LED is about 100x brighter. Unfortunately the efficiency is woeful.

Sounds like a fun project. And if it fails I can always just buy one, haha.

I use these. Standard house key with a built in LED light. They work very well.

Yeah but these stay on for ‘years’. Some of mine were built in 12/11 and are still running the original batteries. When I get up in the morning i can find my keys without even looking for them because they are glowing green. My GF has a green and pink on her keys. I used to think tritium was the way to go, and there are some instances were it’s definitely the way to go like watch vials and gun sights. But in this case it’s way brighter and replaceable and still lasts for years. It’s hard to convince nonflashoholics how cool something is like this, but when people are like, “your light is on.” Then you are like “It’s ok it stays on for years.”
BTW I do mean to get to Home Depot to get a couple of the new Cree bulbs. I think they are 12.49.

Wow, those are pretty sweet

I’m glad I’m not the only flashlight collector out there, I was beginning to think I was strange.

Just a heads up, Lambda says the nano ones should be ready next week Smile Still been super quiet over there and the administrator has been quiet for several weeks. I know they just renewed the domain then nothing. http://flashlightnews.net/forum/index.php?topic=2897.0 I might pick up one of these to check it out. The ones I’ve been using on almost all my keys have been great. I try to keep my keys in the same spot when I get up for work, but they are so much easier to find when they are lit up.

Any idea when this build may start? The turbo 3 was in November, but I don’t see anything on the turbo X. Just wondering

Not heard anything yet about another build. I received one from the Nov build with the top bin SBT90. I see the price on that LED has come down, like they all do. It was 79.99, DigiKey . This is still the most impressive LED light I’ve used. JMPaul measured his VPT3 @ 364K Lux, I believe. 1,538 Lumens at the rated 9A, only thing though these are driven at 13-16Amps, so I think emitter lumens should be more than 2000! I’ve manage to pull together quite a few of the Lambda lights. I believe right now I have 16 Lambda lights; Five of them are VPTs ( 1 SBT90, 1 Dedomed SST90, 1 SST90, 1 XM-L, and 1 XP-G2) and 3 of them are Hydra multiXML (2 3XM-Ls and one 4 XM-L), 12 of them have the VaraControllers and the 4XML Hydra has the VaraLevel. The others are single mode c and D low voltage/high current XM-L mods.

Really good stuff and that’s why I get it and every iteration has been considerably better than the last. For instance, this,(L) is a copper bonded DeDomed SST90 regular Varapower V the (R)VPT3 SBT90mb. The Light on the left still has an OTF lumen of around 1700 and will be impressive to lots of people. I doubt the Olight SR95UT was using this flux bin (MB) since it is considerably more expensive.


But I don’t know any lights that come close to the LUX at even 1/2 the output.

the price on the nanos is $15 each and 12.50 if you are a FNF member (source – lambdas post)

the only thing that would get me to sell my VPT3 sbt90 mb would be a VPTX XPG2 @4amps with aspheric option

my VPT3 puts out about 75% the lux as my TN31MB with a hotspot nearly twice as big, and the aspheric setup is nice also – makes quite a nice LARGE square beam Smile

Would you mind keeping the wrong flashlight?
Best wish, May

This isn’t updated, since I’ve acquired some more

How long does a standard fauxton led light up until its totally empty?
I have one of my old ones with blind led switched on after seeing this threa(50 hours ago) and it still is burning…
