Short Review

From the first instant this light was mentioned, it was immediately compared to the Olight Seeker. Well, for me, that’s great because I love the Seeker! That the Acebeam E75 flashlight is available with four Nichia 519a emitters is a massive win by Acebeam, and makes the light easy to recommend. If you’re in the 21700/quad emitter/high output search, the E75 is a great choice!

^ Measurement disclaimer:  Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

What’s Included

• Acebeam E75 Nichia flashlight
• 5000mAh 21700
• Charging cable (USB to USB-C)
• Lanyard
• Spare o-ring (2)
• Spare charge port cover
• Manual etc

Package and Manual

Build Quality and Disassembly

It’s an Acebeam, so you’d expect (and get) very good build quality. I have historically not been a huge fan of spirals on flashlights and have to say that’s probably one of my least favorite features of this light. (I’m a big fan of good ol’ fashioned knurling!). But these are subtle and shallow and look and work just fine, so it’s all good. They certainly don’t detract from usability of the E75.

On the other hand, I am a big fan of the bezel. I like it both because it seems very robust, but also because it has the teeth, and even more so because it follows the last year or two design theme from Acebeam. This light matches the other recent Acebeams!

Inside the cell tube, both head and tail have springs.

The tail spring is very beefy. Though I didn’t try, I think the spring can be removed and the tailcap magnet probably removed, too.

Size and Comps

Size: 129.3(Length) x 35 (Head Diameter) x 28mm (Tube Diameter)
Weight: 145g(5.11oz.) w/o battery, 217g/7.65 oz w/ battery

If the flashlight will headstand, I’ll show it here (usually the third photo). If the flashlight will tailstand, I’ll also show that (usually in the fourth photo).

Here’s the test light with the venerable Convoy S2+. Mine’s a custom “baked” edition Nichia 219b triple. A very nice 18650 light.

Also above is the light beside my custom engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 formats. I also reviewed that specific edition, the “Oveready BOSS FT Collector Vintage Brass” 35. I love it!

Retention and Carry

Included for carry of the Acebeam E75 Nichia flashlight is this two-way screw-in pocket clip. The pocket clip has a lanyard hole, too.

The clip is held in place by these two screws. Note that the USB charging port cover is also captured by the top edge of the clip. This is a nice thoughtful design. It should also make replacing the charge port cover easier.

In the tailcap is a decent-sized hole for attaching the lanyard.

This tailcap magnet is quite strong!

Power and Runtime

Power to the Acebeam E75 Nichia flashlight is from a single lithium-ion cell. My package included a cell, and this cell is included at the purchase price. The cell is a 5000mAh 21700.

The cell is installed into the E75 in the usual way – positive terminal toward the head.

Below are a few runtime tests. The light shuts off when cell voltage is low (around 3V).

I love these flat output from Acebeam. I find this to be very trustworthy, even if “trustworthy” isn’t the best way to describe it. Just… if Acebeam does this aspect of the light right, there are so many other things that I don’t even understand that I trust that they’re also doing right.

Charging

Acebeam incorporated USB-C charging into the E75 itself. The charging port is in the head and is protected by a press-in silicone cover that again, is secured further by the screw-in pocket clip.

A USB to USB-C cable is included.

When charging, the LEDs surrounding the switch light in red. When charging is completed, these turn green.

Charging is quick at around 2A, but then holds for hours at a very low current. In reality, “full charge” takes about 3 hours (reasonable), but will sort of continue for a long while after.

Modes and Currents

Pulse Width Modulation

The Acebeam E75 Nichia flashlight does not have PWM in any mode! That’s great. And one of the things I love about Acebeam flashlights.

Here you can see a “baseline” – a chart with almost no light hitting the sensor. Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.

User Interface and Operation

The Acebeam E75 Nichia flashlight uses a single e-switch for operation. The switch is much like on the other namesake X75 (except obviously that the E75 doesn’t have a handle, and just has one switch).

The switch doesn’t have any indicator function but surrounding the switch is an array of emitters that do indicate various things.

Action on this switch is low and pleasant.

Here’s a user interface table!

State	Action	Result
Off	Click	On (Mode Memory)
On	Click	Off
On	Hold	Mode advance (Low>Med1>Med2>High)
Unlocked	Double click	Turbo
Turbo	Double click	Memorized mode
Unlocked	Click 3x	Strobe
Off	Hold	Moonlight
Off	Hold >2s	Lockout
Lockout	Hold >2s	Unlock to Moonlight
Lockout	Click	Switch LED array blinks red and green

LED and Beam

The emitters used by Acebeam in this light are four Nichia 519a in 5000K with 90 CRI. This is a great combination. They each have a small reflector, too.

Again, I like the toothy bezel. This one in particular is not sharp but might be a bit more aggressive than you’d guess. I like it quite a bit.

Acebeam included one of these wands in my package. It fits nicely and works well.

The wand will not change runtimes, of course.

LED Color Report (CRI and CCT)

Acebeam claimed 5000K and 90 CRI for the Acebeam E75 Nichia flashlight and they were right on. The light ranges from warmer than 5000K (at around 4600K) on the low levels to right at 5000K for turbo. CRI is also much higher than 90, at around 95. This is incredible output!

Beamshots

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level and the beam hits the ceiling around 9 feet away.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!

Conclusion

What I like

• Great output
• Nichia 519A in 5000K and high CRI is an option
• User interface is nice and easy (also familiar to Acebeam users)
• The switch LEDs provide useful information
• A stainless bezel matches the

What I don’t like

• I don’t love spirals like these (but wow what a truly trivial thing to mention in the What I don’t like section, am I right?)
