Product Description
An excellent tool to have on a keychain, the compact Lumintop Geek flashlight pumps out 350 lumens and offers multiple modes for different scenarios. Made from lightweight aluminum alloy, it has both a front light (with six modes) and a side light (also with six modes) Read More
I bought the Lumentop Geek for $60 and ended up returning it but at $35 it's way more reasonable (recommended, even). I have my gripes against the light but I'm sure my thinking was influenced by the price I paid for it.
Build quality is GREAT. The machining is precise and the flashlight is comfortable in hand. Its overall size makes it more suitable for carrying in your coin pocket w/lanyard than on a keychain. The Geek is also sealed off with rubber gaskets and flaps (for the MicroUSB port), making it seem more water resistant than my MecArmy sng5 or Nitecore TIP.
The main CREE LED is bright and stepped well but the TIR lens makes the light a little too floody for my tastes (compared to my Nitecore TIP and MecArmy sgn5). This makes it a lesser thrower than those two other lights.
I also almost never used the Nichia LEDs. It would be great if for the next version Lumentop could somehow make the diffusion screen covering the Nichia LEDs lift off the body a little (for example, think the Nitecore LA10). I think it could successfully turn this gadget into a flashlight/lantern combo.. unfortunately, as it is the Nichia LEDs are a bit too unidirectional and aren't bright enough for their runtimes.
Finally (and this was the deal breaker for me), the UI is wonky. Strobe mode is only available if the light's memory is already saved on moonlight mode and the light turned OFF. Strobe won't work if the memory is saved on any other mode. I also couldn't get beacon or SOS to work no matter what I tried. Most annoyingly, the Geek doesn't have independent memory for the Nichia and Cree LEDs. Another way of saying this is that the memories (the brightness steps) are tied between the two lights. You will be pressing the buttons A LOT if you plan on using both sets of LEDs.
Oh, and it has the word "Geek" printed in like 20pt font on the back of the light in a really unflattering typeface... but we all have different tastes :)
So at $35 go for it! That price makes it competitive with all the other keychain flashlights on the market (MecArmy sgn3/5/7, Nitecore TIP, Surefire sidekick, Manker LAD, etc.). The ability to switch to HCRI Nichias are a novelty but unique all the same. The build quality is also assuredly better than the other lights.
Drop Organizers; Thank You!… for including a photo with the item in hand. It helps immensely to grasp the actual size and volume of the item being offered.
Too many drops present sterile photos of the items with nothing to convey the relative size of the item in real-world usage. Thank You! 🤗
glennacBut is it a big hand, or a small hand?
seriously, I do think some reference of scale is very very useful to show, but a hand isn’t enough for me. Step in the right direction though!
Oh, I wish I could send you a PM!
But here, I agree with you, the lumen rating is probably based on how the light is measured, which may favor wide floody beams over concentrated throwers. IMO, this light still seems functionally ideal.
EvshrugYeah, I kind of wish there were better number metrics for lights, as currently they rely on those little images on packaging to give a rough idea on the throw and concentration of the light. Then maybe people wouldn't be tricked so easily by all the super cheap lights with ridiculous lumen ratings.
I am /u/DireCyphre if you need me for something!
This is neat looking! I have been looking for a light with a "side light" as they call it here, for a long time. I'd really love to see a video to get a bit more sense of the modes and how the light looks. But this is compelling to me.
applevisionI actually answered my own question! It has high-CRI Nichias on it and is even more interesting than it looks here! See the official page here: http://www.lumintop.com/geek.html

The thickness and weight difference is REALLY noticeable to me -- the Lumintop Geek is way too chunky to go on a keyring, for me, where the TIP is barely there. I prefer the TIP's interface but the Geek's interface is fine.
The Geek is very rugged and well-made, and I have no problem believing that it will stand up to more abuse than a TIP. It's also more flexible with the side light.
I got a Geek on a previous drop and don't carry or use it much. That doesn't make it bad, it just doesn't work as well for me. I like the TIP a lot and use one all the time.
I've never been a fan of any Lumintop light UI, where Nitecore has it down now with their 2 button options that gives access to instant low and instant high, and by keeping it consistent across most of their models.
Which lights here at MD offer ‘instant High’ AND ‘instant Low’, and is pocketable?
Every light I’ve come across cycles through one arrangement or another of L-M-H.
glennacMost of the current Nitecore lights have the options; currently the only active Nitecore drop is for the EA45S that uses 4x AA.
For a keychain light option like this one, Nitecore has the TIP model that also has instant low/high. They can be found from many different online stores.
I also noticed this now and looks like it was mentioned once before, but those specs are definitely wrong. No way a High CRI Nichia LED is going to get nearly 4 times the runtime of the XP-L in the front while outputting the same amount of lumens.
An independent review and test shows that the side light definitely has a shorter runtime than the front light on high mode.
