TK's Emisar D4 review

Thanks for this!

Thanks to all involved in the creation of this little monster …
Arrived today:

I will definitely use it with Sanyo GA( Is more than enough for me) . It is a hand burner in 15 seconds, even after the step down …. I will have to reset the “thermostat” of the flashlight :slight_smile: I love it !!

D4EVIL inside indeed! I like it

I think the light’s dark front area may have eaten some lumens compared to a light which doesn’t have that. After recalibrating for that effect, I think it may have been doing 3241 lm instead of 2818.

The graph a few posts ago (with 4848 lm) was done after recalibration, and both lights were measured with the same setup to keep things consistent.

I wanted to see how the shape of the output curves compared at a similar level of power per cell when thermal regulation wasn’t a factor. It seems the Meteor is partially regulated at first, then drops off starting at a fairly high voltage. This continues until it gets down to a pretty low level, and then it blinks to indicate low voltage. The D4 has more of a typical direct-drive (ish) curve until it detects low voltage, at which point it blinks and steps down to a stable regulated level. Although not shown in the graph, it then stays until voltage is low again, and repeats the blink-and-drop. After doing this enough times to reach the lowest level, it finally shuts off. Based on other tests, it looks like the first stepped-down level would probably last 30-40 minutes, extending off the right edge of the graph, and then the next level might take even longer, so I didn’t wait for those.

The Meteor has more area under its curve in this test, though it’s not clear how much of that is due to a more efficient driver vs more efficient emitters (D4 used 219c, which is significantly less efficient in this configuration). But while the Meteor was running at maximum output the whole time, the D4 was at only 1/3rd its maximum power. It’s a bit like comparing a commuter car to a race car. They are good at different things.

Got mine and a couple others today.

Man this thing gets hot in literally 2 seconds. May have to get the Xp-g2.

They look good together.

Highest it got was 128f.

figuring those O-Lights aren’t getting a whole lot of attention :wink:

I’d say they look absolutely fabulous together.

I honestly can not stop touching the D4. Fiddling, fiddling, fiddling… fiddle… fiddling, fiddling, fiddling… Hold on gonna get some coffee.
(1 minute later) I’m back. Fiddling, fiddling, fiddling…

I do like the simplicity of the charging. Fit and finish is great. Good UI. HAS NOTHING on the power of the D4 though.

For a good time, press the S30R tailcap against some steel wool.

… and you thought Olights aren’t exciting. :smiley:

Got my D4s in the mail today. A 219c and a xpl-hi both 5000k. Perfect edc light. And ToyKeeper did a excellent job on the ui v2 tweaks.

Wow! It doubles as an emergency fire-starting device! :smiling_imp:

Caution, anachronism penalty warning, do not carry the S30R in the pockets of your chainmail suit

You guys didn’t know that? Says it on the website.

Got shipped from intl-outdoor (219c) on july 31, paid for a tracking (hk post), until now, the tracking is not found… Ordered another one (xpl hi) from intl-outdoor 2 days ago, paid for the tracking, didn’t received tracking number, send 2 emails, no response. I am a little bit worried about intl-outdoor,

Any advice?

I added tracking the next day. Took a few days to show up but worked great.

I got my tracking number after 5 days of order placed and shipping notice on the 10th day, i should received my D4 today if not then it should be on Monday. So total transit time 14 days not bad. Could be the worst weekend for me :disappointed:

Hank is a trusted seller here, dont worry you’ll get your D4 it just take time.

I just noticed that Richard is largely out again.

But the shocking thing is, that there are no reviews on his web site. Now that is a crime. :wink:

Come on team lets show the love.

Ok my D4 might arrived on Monday, the mail man came today and only bring different order so No D4 for the weekend :cry: got to wait till Monday.

Mine reached my home yesterday. Grey with 219C. Get scorching hot in 20s, that thing is insane !
The UI is a joy to use, I set the temp setting and tested all the little details of TK UI. A true gem for 40 bucks !
