Hello,
I’m looking for a small light (about the size of one that would take a single AAA battery) for reading at night.
I’d like one with a dim or dimmable light that is also amber or doesn’t contain any blue light?
I’m in the UK so my options will be limited but hopefully I can find something.
Thanks
have you considered some of the old Incan lights? that`s what I use at night for reading in bed, but if it has to be pure amber (LED) then you Can get both E10 MES and PR 13.5 flange type fittings with LEDs mounted in different colors on ebay, that will go into the old incan lights no problem! 
I also think this is a great option. Note that if you look at spectrum, you will see a small spike in the usual place at in the blue range. I have not found any research showing that this is a concern compared to smoother spectra of the same color temperature. I’m pointing it out in case this matters to you, but I suspect a low power 3400K LED like this has pretty minimal effect on melatonin suppression.
The spectrum in this post should be for the same LED:
Thanks - the warm white 3400K option?
I actually have a Thrunite Ti3 that has a dim firefly mode which is 0.04 Lm:
The Ti3 is the perfect size and the brightness is good but I worry that it is too blue and might be disrupting my metalonin production?
Is the light from the Ti3 different to the Sofirn C01?
I also have a Thrunite T01 but that is way too bright. But is it possilbe to get dimmer bulbs or change them somehow to be less blue?
Thanks
> Is the light from the Ti3 different to the Sofirn C01?
yes the C01 is a High CRI LED, it has a LOT more Red spectrum
I would use the C01 3400k, like samyy said
here is an Amber option:

> The Ti3 is the perfect size and the brightness is good but I worry that it is too blue and might be disrupting my metalonin production?
it is indeed a blue light source, but at the firefly level, the amount of blue is likely insignificant… or, are you having trouble falling asleep?
you can swap the LED, if you learn to disassemble, and solder in new LEDs, or hire help to do the job
you Can just buy Amber leds, not the blue ones with the phosphor coating, but propper amber light direct from the Silicon itself, no blue (or other colors) at all 
Are you also using tint shift on any electronic devices? I didn’t pay much thought to that kind of thing until I tried it on my computer. Instant improvement in my sleep.
In the other forum, Vinh Nguyen is offering Manker E02 II’s with various alternative LED’s. One is SST20, 3000K. That has 95 CRI and a pleasant amber-ish cast to the light. It also offers around seven light levels and runs on a AAA.
excellent suggestion, because of the very good selection of sublumen levels
here is the purchase link… get the 4000k
that price cannot be beat, and it includes the headband
Since you have been using the Very Low Low on the Thrunite, I think the Sofirn C01 would be MUCH too bright.
Get the Manker instead.
Buy High CRI, not amber…
the Manker is the only AAA light with multiple options for a firefly low that is as low as the Thrunite you use now.
I checked the SkyLumen site and it says that the Manker E02 II is sold out. E-mail Vinh anyway and tell him what you want. He’s already had one encore batch of this choose-your-own-LED light in response to popular demand and it might be possible to get him to do a second one.
Note: I got E02 II’s from him with SST20 3000K (which is the combination you probably want) and 419b 4500K. They’re very nice and maintain the ultralow light levels that jon refers to. However, a third E02 II with a XPE-2 red LED didn’t have the low levels. Apparently there was a problem with the combination of the driver and that particular LED.
UPDATE: Vinh tells me that he’s just put them back up on his site a third time, but the number will be strictly limited. That’s because he’s charging about the same for the entire light as he normally would for replacing an LED. He’s also added 219b @ 3500K and 4000K to the options. Order while you can! Jon’s link above is to the page with the stock light. Here’s a link to the page with the pick-your-own lights: https://skylumen.com/products/manker-e02vn-ii-you-pick-led-limited-run
Thanks, which one should I choose?
Do you think he would ship to the UK?
Here are some option:
XPL2 6500K
XPL2 3500K 80CRI
Nichia 219b 3500K 90CRI
Nichia 219b 4000K 90CRI
Nichia 219b 4500K 90CRI
SST20 3000K 95CRI
SST20 5000K
SST20 6500K
XPE2 Red
XPE2 Blue
XPE2 Green
XPE2 Amber
I do on my phone and laptop but not my TV.
I have some blue blocking glasses from Amazon but not sure how effective wearing them is.
Welcome to the forum!
You can get a flashlight with ramping capability, which will allow you to use any brightness between minimum and maximum.
Most warm white flashlights emit a significant amount of blue light.
Some amber leds also emit blue light, because there are 2 kinds of amber leds:
(1) narrowband amber (single color only, led is based on an amber chip)
(2) phosphor-converted amber (all colors with peak output in the amber area of spectrum, led is based on a blue chip with phosphor on top)
You can still see colors with a phosphor-converted amber led, you cannot see colors with a narrowband amber led.
If your goal is limiting blue light, and you don’t care about seeing colors, your best bet is a flashlight with a narrowband amber led. XP-E2 Amber is a good narrowband amber led.
If your goal is limiting blue light, and you care about seeing colors, warm white E21A 2000K R9050 is a better choice than phosphor-converted amber, because it has a very low amount of blue light and great color rendering.
I recommend XP-E2 Amber.
If use of AAA batteries is not a strict requirement, you might want to consider Emisar D4V2 or Noctigon KR4 with XP-E2 Amber emitters. They are not available as an option on https://intl-outdoor.com/, but you can order a custom flashlight with those emitters if you send Hank an email. You can find his email on his site.
Custom Emisar D4V2 with XP-E2 Amber would be bigger and slightly more expensive than Manker E02vn II , in return it would be a lot brighter (it has 4 leds, not just 1), with much longer runtime and optional magnet in the tailcap. It uses Anduril software, which is popular and has many useful features, such as ramping modes where you can customize the maximum and the minimum level, and flickering candle mode with optional timer.
I have a custom Emisar D4V2 with XP-E2 Amber that I purchased a month ago.
Thanks!
I’m not bothered about having AAA but that is the sort of size I am looking for.
My wants are:
The Emisar looks good but might be too big and bright?
Thanks
Manker E02vn II with XP-E2 Amber sounds like a good fit.
Emisar D4V2 with XP-E2 Amber can be a lot brighter, but you can choose the exact amount of light that you need, because it supports ramping. Minimum, maximum, or anywhere in between.
Thanks. So can I ramp it up and down via the device, such as twisting it? Or is it set some other way?

Ask him! skylumen54@gmail.com.
Keep in mind that he’s only offering 7 more of these pick-your-own-LED versions of the E02 II in this batch - and I’ve ordered one of those already.
I think for night reading you would want a SST-20 with 2700K.
Barry is making a new headlamp D25 White+Red and it might be perfect for handsfree reading;
