A few days ago, I received the FF E07x with the new FFL351A 1800k emitters and X1L XHP70.3 HI 4500k and had time to extensively use the E07x.

For the past 7 or so years I've been wishing for a high power 90+ CRI 1800k candle light and camp fire simulator. The only ultra warm hi CRI emitters that existed in this category were the Nichia E17A 1800k and E21A 2000k but those were not high powered and were found in only a few lights. There is also the GT-FC40 1800k emitters but their tint is so far above the BBL (+0.070 duv) makes it look nothing like candle light and is horribly yellow and I hate yellow or green tint. I was afraid this new FF 1800k emitter would be like the GT-FC40 1800k but thank God the tint and performance is similar to the Nichias but much higher power. The DUV is basically zero, which is perfect for ultra warm candle light simulators since candle light and campfires have DUV of zero. I normally like negative DUV but only for higher CCT lights, for ultra warms, DUV between 0 to -0.002 is ideal. Too far below the BBL, and the tint won't look natural.

For those wondering what are some benefits or reasons for using ultra-warm lights. Here are a few off the top of my head.

  1. exposure to blue light at night, especially from bright lights suppresses melatonin production (a hormone that regulates sleep and has anti-cancer properties) and increases cancer risk. There are sleep bulbs on the market that are advertised to help you fall asleep and reduce insomnia but all it really is, is an ultra warm cct light bulb and the ones I've tried in the past are all yucky yellow due to the very positive DUV, which is similar to the GT-FC40 1800k.
  2. Some children prefer to sleep with lights on or at least with a night light, but blue wavelengths can inhibit their melatonin levels and hence reduce grown hormone production. I've been using a E21A 2000k flashlight as night light in my kids' room but will be switching to the 1800k.
  3. Insects are attracted to blue light. If you use a CW, NW, or even conventional WW light during camping or night hiking, you will notice how it attracts annoying insects. Using an ultra WW light will alleviate this problem.
  4. Many nocturnal animals are extremely sensitive to blue light because they will detect it as sunlight or danger and will hide immediately when they detect blue light. Blue light at night can also harm or misorient many nocturnal animals. And of course for anyone that enjoys the feeling of being immersed in candle light or camp fire atmosphere will surely appreciate a clean tinted hi CRI Ultra Warm light. For me, this light is like a dream come true and I find myself constantly playing with this E07x daytime and night time! Anduril's candle mode complements this 1800k light perfectly to create the ambiance of a flickering candle or cozy fireplace. The wine red E07x is also one of the most beautiful lights I've ever owned, looks much better in person than in my photos.
  5. Blue light hurts your night vision. The less blue light, the better you can preserve your night vision. Using an ultrawarm light can achieve this and still perfectly render colors unlike monochromatic red or amber LEDs that are normally used for this purpose.
  6. Blue light has a shorter wavelength than other colors of light, so it scatters more when it hits water particles in fog. This scattering can reduce your ability to see through the fog, and it can also increase glare because blue light scatters better inside your eyes. Lights with less blue wave length will pierce better through the fog.
I do have suggestions for FF to further improve this light though. While the LUME driver is one of the best and most efficient regulated flashlight drivers, I just wish we can have a FET turbo mode to allow the output to go all out like the original unregulated E07. Also FF might consider offering optional Green AR lens (that blocks green tint) to lower the DUV. Right now the duv is about 0.008. A green AR lens should bring the tint down just enough to reach 0.000. I'm just being nitpicky here.
EDIT: I just realized it does have Green AR coated glass lens. Now I just wish there is an optional stronger Green AR coated lens to lower the DUV further.

Below are my light measurements using the Texas Ace Lumen Tube and Sekonic C-800-U spectrometer. Please note that light meters are less sensitive to warm cct and reads higher lumens for cool cct so actual lumens should be a bit higher than measured if comparing to cooler temp lights. I included two other ultra warm category lights for comparison.

I am not a fan of yellow or green tint shift either.
Nice clean warm tint!

What is the finish on the (SS?) bezels?

How's build quality, are threads smooth, any sharp corners or burrs didn't come off before ano..?

Thx..

Black stainless steel bezels. Build quality is top notch. I heard FF is using the same coating company that does the anodizing for Olight, which is why it feels so premium now unlike the typical budget flashlights. FF's quality improved significantly over the years.

Thanks for the heads-up. Will have to give their offerings a closer look.

It seems that the expensive

E07X

flashlight is the only one that can be had with the 1800k emitter?

Where are these lights available? I can't find anything on them?
FireFlyLite had issues a few years ago. However lately they have really stepped up their game.

Recently purchased E07X 5000k. Now I am considering NOV-Mu 3700k, 9 LED's squared up in the center (mule) 6000lm turbo for a few seconds,1400lm constant running with a really sweet moonlight beam

Ordered one of these (FFE 07x with 351a). My take on it.

Pros
Like the warm tint for a change
Like the magnetic charging port door.
Like the grippy housing

Cons
The UI is the worst I have ever seen. 7 clicks to select one of the menu items??? Holds (which are not really holds) and clicks...yuck!
Instruction booklet is horrible. I did not see anywhere in it to turn the head of the light to engage the battery. Took a while to figure out I did not have a dead light.
Just kind of a very weird to use light.

Wish I would have used the $100+ on a different light. This one will likely find the back of a drawer somewhere.

FFL ships with 21700 Vapcell in body..
Unboxing the very first thing I noticed is head was backed off body locked out for safety.

Imo, Anduril2 is one of the most ingenious UI's to date.

Getting ready for bed I can actually get myself under sheets and the flashlight turns off automatically. Moonlight has a delayed off, lol

Only complaint, my flashlight doesn't say (yet) Goodnight Knucklegary sweet dreams (-;

** Hope this helps, posted in couple threads here by @jon_slider (for us muggles)
