What is the brightest red LED flash light out there?

What is the brightest most lumen red led light out there.

Off the shelf retail RED flashlights are limited. The better ones are based on the Cree or Luxeon emitters. Output on these are in the 50 lumen range despite what Sellers claim. From there the next step is custom led flashlights. You can DIY or have one made. Most of the higher powered custom flashlights will be made with Luminus red leds. Nailbender on CPF offers RED SST90 customs. Jayrob (CPF or LPF) has instructions and sells items based on his custom RED PT54 build. I build my own direct drive PT54 & PT120 for personal use.

Does that mean the Solarforce colored LED drop-ins are not 225 like they say?

Look it up, e.g.
Cree XLamp XP-E LED Data sheet
www.cree.com/products/pdf/xlampxp-e.pdf
… amber, red, red-orange …

Olight M20s crimson is 105-110 lumens of red. And the Zebralight H51r is 90-100 lumens.
I own the Zebralight H51fr and it’s rated at 90 lumens, it’s brighter than the most the red dropins I’ve bought, except VinhNyugen’s 2amp xre dropin.

I think an Sst90 red could be brighter, at 3 to 5 amps. But heat would be an issue for running it for more than a few min

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

The flashlight wiki says the XRE R2 LED is capable of 250+ but the driver could well limit that depending on actual draw (and the Cree documents add that it varies slightly by color) . . .

. . . but not having a draw figure on the SF website I asked about the posted experience.

225 is possible (maybe probable), but we have conflicting info on the SF website about P4/R2 bin and from someone posting above. Still wondering.

225 lumens of red, might not register as 225 lumens in a light sphere? Would be my guess

It may be possible with the proper heat syncing, if you maxed the safe amperage. My Vinh made dropin, which is run at a higher amperage than I thought safe for an xre might be 200+ lumens calculated by lumines flux, voltage and amperage but it I couldn’t tell you if it actually was.
The xre and xpe are 625nm – 630nm, which isn’t a deep red but still fun.

I guess it depends on what and how the meter reads that WL.

Supposedly 200 is doable with only 0.7A for this bin. But you raise the question of whether the WL will work for my son (not spooking hogs).

You may want to look into a deeper red, 640-680nm. Get E1320 to make you a 3watt dropin, you won’t need more than 40-60 lumens with night adjusted eyes.
Smooth reflector for some throw

You could also turn just about any light you have into a red, blue, green, amber light by using colored lenses. Not as efficient but if you start with a 800 lumen light…………….

Good input, guys. He found a cheap red 501b on DX but he may get the SF high voltage drop-in since he wants something in single mode and I have hosts. Or maybe in time both to have parts for a custom.

Fenix store has diffuser lenses that fit some diameters and there $6 ish
If you get the 501b let me know how good it is Smile

The DX 501b have red XR-C at least the one I ordered did. Typically red diffuser lens used on white leds will severely deplete output.

Really appreciate getting more input. Apparently the DX reviews say something about Crees instead of the spec’d LED . . perhaps the product is slowly getting updates based on led cost and availability.

Edit – I guess the other question is if you got an XRC, did you get something worse than they spec’d? My quick review suggests the K2 might be much better than the XRC?

The DX ad IIRC states Luxeon K2. In the last year or more Cree have been sent. The Green I ordered had a Cree XRE. The Red had Cree XRC. Guess my older Cree pdfs are out of date as no Red XREs are listed. Read the newer pdfs and suprise RED XREs. Mouser or Ledsuppy doesn’t list them. Who has Red XRE stars?

Always something new and in a quad die. Where can I get one?

I picked up a PT121 red less than a month ago. 2000+lm

Built a green PT120 aspherical last fall.

I’m pretty sure they can be purchased direct from led engin. There is a phone number on that link to request quotes.

“I picked up a PT121 red less than a month ago. 2000+lm”

Nice! 2225 red lumens @ 30amps. I would love to have one of these built into a drop-in of some sort for one or any of my lights. Not in either of my Hellfighters, obviously.

Been getting my PT54 reds from DTRLPF for a while. Currently he has new pulls cheap 6@$50 on Ebay.

I bought a red xre from goodluckbuy.com havent used it yet. I also ordered the green xre from goodluck and installed it in a small sun c10 flood to throw and its pretty sweet. It throws good, throws easy 500 feet.

Havent tested the light out in the field with a scope but should be more then bright enough. Its only driven at 1.1a but thinking of doing either direct drive or a 1.4a single mode driver i have.

Willie is the man on colored leds.
Installed that pressure switch on the small sun that you suggested to me and works good.

This is the brightest RED light i know of it won’t be cheap but a red SST90 should be a bright as your going to find anywhere

Lambda has inspired some of my direct drive builds. The SST90 is actually a little less powerful than the PT54 and is no match for the PT120/121 series.

http://budgetlightforum.com/node/9101#node-9101

This was with a 8A build.

And PT120 green build.

While that is definitely a good start, I found that my ET T20C2 MKII XML with a red filter isn’t nearly as bright as using the red LED drop-in in the same light. I use red and green frequently and have been thoroughly pleased with the red drop-in for my EagleTac.

Some really great stuff here . . . great pics on I think it was the TR1200 build or next link, willie! Did you ever do a thread on building those feeder lights? Solar powered?

How about one of these 5 XRE lights and we swap them all for red XREs that would kick some serious ass.

Just finished soldering a triple XP-E red (in N3 bin) to a modified (so each LED is individually regulated to 700mA) 2.1A driver. From the specs it should be between 300-330 lumen. All I have left is to get a P60 drop-in shaped piece of aluminum machined out and I will have a 50m+ bunny torch. Awesomely bright for a red torch however the soldering took me many hours to get right. I will stick so photos up if I ever get it finished (I started at least 2 months back).

As far as I am aware the XP-E N3 bin is the best there is when it comes to efficiency vs red output. It is about 62 lumen per Watt. Wavelength is 620-630nm. I got mine from Cutter electronics in AU.

Really not much to build them. I used two 3up XPC (typo xre in post) & and a 1400ma buckdrive from ledsupply. Wired the 3up in parallel to each other for a conservative 700ma. Put a switch on the buckdrive to toggle a resistor to 350ma for everyday use. Only run with 700ma when hunting that stand to minimize battery drain. Lucked into the following 48w panel and 85lb large AGM battery for CHEAP. The brains and control is a solar street light controller that regulates the over or under charging of the battery and is programmable for runtime or dusk to dawn. Uses the solar panel for a light sensor. One like this. http://www.ebay.com/itm/10A-12-24-Auto-Distinguish-Switch-PWM-Solar-Street-Light-Panel-Charge-Controller-/280882460728?pt=LH_DefaultDomain_0&hash=item4165e63838

On my smaller setup have used this

Found most of my panels and batteries used for cheap local on Ebay, Craigslist as shipping kills most deals on these items.
