LEP + LED flashlight: Lumintop Thor Pro [discussion + review]

Lumintop Thor Pro prototype review

Note: Come back soon for more info. I’m trying to share what I can before Christmas.

First impressions

This thing is really cool! It’s a LEP flashlight that has enough flood to see where you’re walking. It doesn’t run Anduril but Lumintop’s 2 channel UI works really well. You can run just the LEDs, just the LEP or both at the same time.

This prototype uses XP-G3 LEDs. It hits 7000 lm and 500kcd (1400km) with low current cells.

Quick overview video:

Box and packaging

This is obviously a prototype. Only the light was provided in the box. No manual, accessories or information.

User Interface

There was no manual provided, so this is what I’ve worked out so far:

  • Click for on/off. The light has mode memory on the main modes.
  • Changing brightness
    • Hold when on to cycle up low-med-high and back to low.
    • The second time you hold it will cycle down high-med-low and back to high
    • Each hold changes cycle direction
    • Always cycles up the first time when turned on
  • Double click from off = high (not memorized)
  • Double click from on = turbo (not memorized)
  • Hold from off = moon, then cycles up the modes
  • Click and hold from off = turbo

Channel switching

  • Mode memory includes LED/LEP
  • 3 clicks to cycle LED, LEP, LED+LEP
  • 3 clicks from off will cycle to the next mode with a quick flash
  • Lighted e-switch: Green (the bunny’s feet) = LED, Blue (ears) = LEP, green and blue = both

The e-switch indicator light is dim when the light is off and bright when the light is on

  • 4 clicks from off = batt check, like Anduril/Narsil. This only uses the LEDs
  • 5 clicks from off = lockout. Blinks to confirm. Allows momentary low but only on LED. 5 clicks again to unlock
  • 7 clicks from off = toggle the e-swich light

Light output: LEDs and the LEP

LEP

The LEP module is a shine-through version (rather than mirror). Most manufacturers seem to be using these now.

There is a 26mm gap in the reflector for the LEP lens.

For comparison, the Thor II has a 35mm inner diameter (41.5 head diameter). The Thor I has a 32 mm head diameter so I guess its lens is about 26mm too. I wouldn’t be surprised if Lumintop has used the same LEP module and lens as the Thor I. Read ChibiM’s review of the Thor I for more info.

The LEP hotspot looks slightly larger and less intense than my Thor II but not by much.

LEDs

This prototype has 8 lots of CREE XP-G3 LEDs. That’s 8 more than I’d normally like :-).

The XP-G3 is good for output but is not known for having the prettiest beam or highest CRI. The XP-G3s here seem OK, as long as you’re not white wall hunting.

My Opple Lightmaster Pro gives a CCT of 6520K and CRI of 70.

Cells, charging, power bank

Size / shape / handling

Here’s what the prototype measures:

  • Head diameter 67.0mm
  • Body diameter 51.1mm
  • Length 157mm

Rough numbers for the optic diameters:

  • LED 15mm
  • LEP 26mm

Weights

  • Without cells 644g
  • With cells 830g

Build / quality / internals

Lumen and throw measurements

Initial measurements. Take these with a grain of salt. My integrating sphere is normally within 10% of other people’s here.

4 cells charged to 4.20V. Cells are Sony VTC5A button tops, rated to 25A.

Throw was measured at 11m at 0 seconds.

djozz has measured a high CRI XP-G3 at 1300 lm, so 8 of them could hit 10,000 lm. 8 * XP-L should hit 10,000 lumens easily enough too.
