Lumintop W1 LED Flashlight Review

There’s a lot happening with the Lumintop W1 LED flashlight. This version uses a LED for throw and a COB that can be white or red for flood. An 18650 is included. Read on!

Official Specs and Features

Here’s a link to the Lumintop W1 LED flashlight product page.

Versions

Two versions of the Lumintop W1 LED flashlight are available. There’s a LEP version and LED – this is the LED! The W1 is available in black (seen here) or silver color.

Price

The Lumintop W1 LED flashlight sells for around $38 and that includes an 18650 cell.

What’s Included

• Charging cable
• Spare o-rings (2)
• Lanyard
• Manual etc

An optional diffuser can be seen below.

Package and Manual

Build Quality and Disassembly

The Lumintop W1 LED flashlight has a nice build quality. It’s what you should have come to expect from Lumintop – nice quality and reasonable price.

More on that charge port later, but it doesn’t have a cover! That’s interesting. The design here is interesting, as this is a comparatively small light to also have a LEP module version!

Only the tail end has a spring -the head has just a brass button for contact. Below, you can see the magnet in the tailcap, too. (It’s probably removable.)

The cell tube is not reversible, as one end has unanodized threads and the other has anodized threads.

Size and Comps

Size 30 x 24 x 118mm
Net Weight About 98g (battery excluded)

If the flashlight will headstand, I’ll show it here. If the flashlight will tailstand, I’ll also show that here too!

Here’s the test light with the venerable Convoy S2+. The version below is a custom laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full post on an engraved orange host right here! Or go straight to GadgetConnections.com to buy your Convoy S2+ now!

In the photo above, you may note that the SRM (standard reference material) flashlight for comparison has changed! I used a TorchLAB BOSS 35 for ages. Now, what you can see as the 18350 SRM is the Hanko Machine Works Trident. While I have not reviewed or tested the Gunner Grip version seen here, I have tested a Hanko Machine Works Trident Total Tesseract in brass. I love the Trident, and it’s a striking contrast next to the inexpensive Convoy S2+, which also makes a great standard reference material.

Retention and Carry

The Lumintop W1 LED flashlight includes a lanyard, which attaches only to the tailcap.

The tailcap also has a magnet, which is plenty strong for holding the Lumintop W1 LED flashlight.

There’s nothing else included for carrying or retaining the Lumintop W1 LED flashlight. Notably, the light does not have a pocket clip, nor is there a gap where one could really be placed.

Power and Runtime

The Lumintop W1 LED flashlight runs on one lithium-ion cell. An appropriate 18650 is included. It’s a flat top, but you should be able to use just about any type of 18650 just fine.

The 18650 goes into the Lumintop W1 LED flashlight in the usual way – positive end toward the head.

There are a bunch of modes and they sort of come in a number of options. The highest output mode is “Combo” which combines high from the white COB with the the spotlight. Output doesn’t hit the specification but my calibrated setup is not really ideal for testing something this throwy anyway. Check the beam photos for the best sense of the output.

The light does shut off with low voltage protection at around 3V. Also, observe the battery indicator on the switch for this information. It’s intuitive as you would expect, but the manual doesn’t say the exact specifications. Generally green means “charged” and red means “needs charging.”

Charging

This is a waterproof USB-C charging port! I love it. It’s nice to not have to fool with a fiddly press-in charging port cover. Second to that, it just looks neat!

An A to C charging cable is included.

Both C to C and A to C charging works just fine and they’re consistent in performance.

Modes and Currents

Mode	Mode Claimed Output (lm)	Claimed Runtime	Measured Lumens	Tailcap Amps
Combo	700-400	2m+1h30m	381 (0s) 364 (30s)	2.27
Spotlight	300-150	3m+2h	118 (0s) 113 (30s)	1.54
High (Floodlight)	400-300	5m+3h	333 (0s) 303 (30s)	1.13
Low (Floodlight)	100	10h	79	0.25
Eco (Floodlight)	8	100h	7.6	0.04
Red	80	4h	53	1.02

Pulse Width Modulation

All modes use PWM. This shouldn’t be a deal breaker.

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 Lumintop W1 LED flashlight uses an indicating e-switch on the head. It’s a nice switch with a hardcover. The indicator can be red or green.

I like that the e-switch is on the head (and not the tail) because that means there’s no inner sleeve!

Here’s a user interface table!

State	Action	Result
Off	Click	On (mode memory, Low or High COB White only)
On	Click	Off
Off	Hold	Red > Red SOS > ECO white^
Any	Double click	Spotlight
Any	Click 4x	Combo
On (COB white)	Hold	Mode advance
On	Double click	Iterate between spot and flood (memory)
Off	Click 7x	Iterate switch battery indicator on/off.

^ Yes, this is the only way to get to ECO white!

LED and Beam

For throw, this non-LEP version uses a Luminus SFT12 in there! Also, surrounding the lens for the lens is a COB which has white and red output. The white/red flood is very floody.

In at least one mode, the white COB and throw emitter may be used simultaneously. You can’t use the RED cob with the spotlight, though.

A diffuser is included – actually in my package it was separate, and the product pages indicates this might be a separate item. It’s neat and fits very well.

LED Color Report (CRI and CCT)

I tested only the three modes of white COB – they are very cool white and have low CRI.

Beamshots

These beamshots always have 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. These photos are taken around 18 inches from the door.

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

Summary and Conclusion

The Lumintop W1 LED flashlight is a very interesting light! For having an LEP version available (in the same body size as this LED version), the white, and red output, it’s remarkably small. The user interface is interesting. In this case, I’m ok with just three white modes. There should be a better way to get to ECO white, though – maybe if it was just first in the mode cycle. Charging works great and I love the waterproof USB-C charging port! And finally, the price – at around $40, this is a low-cost way to get fantastic throw!!

^ 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 I like

• Low cost
• Waterproof USB-C charging port
• Small size for this throwy flashlight
• Charging works great
• E-Switch on the head end
• Switch indicator function

What I don’t like

• Very cool COB white
• ECO white is too hard to get to
• Doesn’t hit output claims (even when accounting for my homemade measuring apparatus)
