What I have today is another Lumintop, in a long line of Lumintop reviews. This is one I’ve been excited about, because it’s Nichia and brass. Unfortunately, Lumintop didn’t want to send brass or titanium, but I’m not going to hold that against them. 🙂 Here’s the Lumintop IYP365 in aluminum, with a Nichia emitter.
There are a few versions of this penlight. There’s black aluminum with Nichia (seen here). There’s also: silver aluminum, a pink aluminum, brass, and titanium. Some combination of those are available with Nichia and Cree.
Going price for the aluminum versions is around $21. The titanium looks to be around $50, and the brass is unavailable. Buy them on Lumintop’s official Amazon store.
The IYP365 is also available on the official Lumintop sales store, for $20.99!!
This is a nice light, and a good way to get into the Nichia game if you’re curious. I like that it’s essentially a two cell version of the Lumintop Tool. The UI is good, and it handles very nicely.

Package and Manual
Lumintop standard packaging here. A cardboard slip fit box, with reliefs for easy separation. The back is printed with the model details, but no product photos.
The manual is more standard-fare for Lumintop. It’s complete, and good enough. Again, no photos of the product.
Build Quality and Disassembly
I said it already, and I’ll say it again; this light has a great feel. The anodizing is smooth and the lines of the pen light are great. There are a couple of brass touches. one is between the head and the body, and the other is between parts of the tailcap. These are completely decorative.
The cell tube is completely separable from the head and the tail. And to answer your question before you have to look later in the review to see if I did it: no the tailcap will not screw into the head. ( 🙁 ) (but really, how cool would it be?)
The threads on the body are triangle cut, and anodized. The threads on the tailcap are triangle cut, and unanodized. Thus, it’s possible to mechanically lock the light out only by loosening the head, but not the tail.
The tailcap has a long thin spring. I’d expect Lumintop intends for the head to be removed for cells swaps. But either works fine. The driver looks to be screwed in, with two leverage points for unscrewing, but I couldn’t budge it.
Officially the IYP365 is 128mm long, 14.5mm in the head, and 12.5mm in the body. It weighs 23g.
It’s a good measure longer than the Convoy S2+, but also much smaller in diameter.
The head is also exactly the same size as the Lumintop Tool lights. Below, see that the copper version screws right on to the body. And works, too! The tailcaps are different, so it’s not possible to use the tailcap from the IYP365 on the Tools.
A pocket clip is included and attached. It’s a collar type, but can be removed by unscrewing the tail. There is an o-ring here, so you won’t sacrifice waterproofness if you opt out of the clip.
The light will technically tailstand, but really only if the light is on. When on, there’s much less play in the switch. With the light off, it’s a feat of acrobatics to make the light tailstand. But you must ask yourself, why are you tailstanding a light that’s not even on? These are the big questions.
Two AAA cells power this light. The light is not compatible with the li-ion AAA sized cell, the 10440. There’s no low voltage protection. In my runtime on high, the cells discharged to a slightly different voltage, too.
I only tested the runtime on high, because the next mode down claims 25 hours….
Output is very stable throughout the duration of the runtime, til about 70 minutes. The light has no LVP, but doesn’t accept Li-Ion so I don’t necessarily see this as a problem. It’ll be very noteworthy that the cells are low, though, because the output drops to essentially nothing toward the end of their life.
User Interface and Operation
There’s but one button on the IYP365, and it’s a metal tail reverse clicky.
The switch has about 1.5mm of exposure, and is very clicky. The switch will travel about 1mm when the light is off, before engaging the switch underneath the metal cap.
Here’s a UI table!
|On||Half Click||Mode Advance (LHML)|
It takes a few seconds for the light to go back to default of Medium.
It’s also possible to loosen and tighten the head to change modes.
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
LED and Beam
This version of the IYP365 has a Nichia 219BT LED. The reflector is shallow and is very lightly orange peeled.
The profile is is mostly spot, with a little spill.
The Nichia 219BT-ness of this light is absolutely fantastic, and I love it.
There’s also a glow in the dark diffuser, which clips over the head.

Random Comparisons and Competitive Options….
Here’s a relevantly filtered page on parametrek.com. There aren’t many (any?) other 2 cell AAA lights that still have Nichia 219b. I consider “b” the best, and so I consider this light to be fantastic for it. If you need a 2-cell light, or don’t consider smaller lights like the AAA Tool to be “pen light” enough, then this is a wonderful option. Particularly since it’s available in titanium (and brass, if you can find one).
The Nitecore MT06MD also has Nichia 219b. I reviewed that light here. These are very similar lights, of course, with a primary difference being that the MT06MD defaults to low.
What I like
- Nichia 219b
- Build quality
- Specialty metal availability (Brass, Titanium)
What I don’t like
- Defaults to medium
Working on more lights! I have a few geeky keychain lights in for review, and a surprising number of chargers. Look for those next week!
