Small flashlight with dim amber or non-blue light?

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!

For night reading I would recommend Sofirn C01 . Not amber, but warm HiCRI LED without any blue.

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:

https://thrunite.com/ti3/

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?

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:

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 Wink

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

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.

XPE2 Amber

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:

  1. low/no blue light
  2. very dim or low light — or adjustable to low light levels
  3. physically small

The Emisar looks good but might be too big and bright?

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;

I have a couple of the thrunite Ti3. Wonderful little light. Most are a pleasure roughly 4000k neutral white. One is much warmer. Almost a yellow, though not amber. Perfect for what you are asking, but of course it was luck of the draw. They are easy to disassemble, though so perhaps an emitter swap would work for you.

Of course the c01 would be excellent as well, though it’s actually larger.

Another though is that maybe a LRI photon freedom in amber or yellow. Very light and compact.

Click and hold the button to change brightness.

Hey! I have the original C01 with the Yuji emitter and it is one of my all-time favorite little flashlights. The light level is “just right” for night reading, small tasks, etc. The run-time is excellent. It’s also a great choice for kids who are too young to not shine it in people’s eyes but old enough to not try to eat it. Silly

How does the 3400K Sophia version stack up? Also, is red version like a single-mode version of the C01R?

I have the C01 w 5600k Yuji and it is a personal favorite. I like the cooler light when modding flashlights. It lives on my Jewelers visor. I like everything about the CRI and Tint

I dont have the 3200k Yuji anymore, so I cant do a side by side with the 3400k Sophia, but they are similar. If you want a warm LED, I say yes to Sophia.

there are subtle differences in the beam
There IS a hotspot w the Sophia, this is due to the aluminium cone being more shiny than the first run Yuji lights, that had virtually no hotspot. The later released Yuji lights did also have a more polished reflector cone, and hence also a hotspot.

I prefer no hotspot, but Im also not bothered by the hotspot that the Sophia release has. I know I can change it if I decide I want to, with a bit of sandpaper to scuff up the reflector cone, only, not the LED

I do not recommend the C01 with 670nm Red LED. I find it too weak, and the beam has bright artifacts in it. Not a nice even beam. Some people have sanded the LED, this makes it half as bright, and still has imo a beam that is not evenly lit.

otoh, I think the C01R is Brilliant!.. 3 well spaced modes, at useful brightness levels. If you want a red LED light, this is the one to buy, imo.

I found that Satco S9489 monochromatic amber LED bulb is noticeably more orange than my XP-E2 Amber flashlights.

Satco S9678 18W/LED/HID/AMBER/100-277V E26
Satco S9489 36W/LED/HID/AMBER/100-277V E26

I have both S9678 and S9489 and I love the orange-colored monochromatic light from S9489. Manufacturer specifications say Amber color – 585nm, but I am pretty sure that is wrong. XP-E2 Amber is most likely between 585nm and 595nm, and S9489 is significantly more orange. S9678 spec sheet does not mention CCT, but S9489 spec sheet says CCT is 1461K.

(1) most yellow: Emisar D4V2 with XP-E2 Amber
(2) half way in between: Kaidomain P60 with XP-E2 Amber and Satco S9678
(3) most orange: Satco S9489

I did not measure the spectrum, but my guess is S9489 could be around 595nm to 600nm.
