Review: Lumintop IYP365 - Nichia Version

Lumintop IYP365 is a portable penlight powered by two AAA batteries with maximum output of 200 lumens on CREE version and 125 lumens on Nichia one. It has three brightness mode (medium, low, high) and operated using metalic reverse clicky tail switch.


I received this nice looking penlight from Lumintop and I was told that IYP365 means “In Your Pocket Every Day (365 days)”.


Unboxing Lumintop IYP365


I received sample from Lumintop two weeks ago, it’s the Nichia version and it arrived inside a brown cardboard box as following picture:

Contents of the package are flashlight, two spare o-ring, and there are two AAA batteries included although their website said that the batteries are not included.


There was no manual book included. Instead, the data sheet is printed on the back of the box.

To avoid accidental activation, Lumintop put stickers on the negative pole of the batteries. A clever method to avoid battery being drained during shipment/delivery.

And here’s the flashlight, a nice looking black penlight with golden ring on the head and tail cap. It has a strong and properly designed pocket clip which is attached securely between the tail cap and the body.

Disassembling Lumintop IYP365


I was eager to see the flashlight construction. It consisted of three main parts: head, body, and tail cap; where the tail switch is located.


The pocket clip itself is secured between the body and tail cap.

Lumintop IYP365 uses a regulated driver to maintain a constant brightness during usage. It means the flashlight will not go dimmer when the battery is running out of its juice.


Looking at the design of the PCB driver, it looked visually almost the same as Lumintop Tool driver although I can’t confirm that they’re exactly the same driver or not.

Upon inspecting the body construction, I found that I was unable to insert batteries from tail side. Batteries can only be inserted from head side after removing the flashlight head.

IYP365 dimension is pretty much similar to Sunwayman P02A, but slightly lighter.

Their pocket clip design are also similar but Lumintop’s pocket clip is slightly narrower. It also has decorative holes and made the penlight look less bulky than Sunwayman’s.

Operating Lumintop IYP365


Lumintop IYP365 utilizes a Nichia 219B LED which is nicely put centered in the head. The head is also decorated with glow in the dark o-ring, pretty much similar to Lumintop Tool.

Combination of Nichia 219B LED and orange peel reflector resulting a good tint color which is comfort on eyes and gives us a true color sightseeing.

Beam spread is approximately 90 degrees as depicted below. There’s actually more spill out of the hotspot that help us seeing in the dark at a closer distance.


12 lumintop iyp365 beam spill


Lumintop IYP365 uses reverse clicky switch located at the tail. Turning on/off can be done by clicking tail switch while changing modes are possible by either using tail switch or twisting its head.


13 lumintop iyp365 operation


Three brightness levels are quite ideal for most everyday carry purpose. The light always starts on Medium because it has no memory, then goes to Low, and later High.


According to the data sheet, maximum runtime is 50 hours on Low and 35 minutes on High mode.


14 lumintop iyp365 operation


It doesn’t support 14450 batteries so never try to put ones in them. Otherwise, you might burn its engine instantly.

Here’s animated beamshot pictures for your reference. The wall is 2.5 meters from flashlight and camera, all taken in manual exposure, 1/4 sec, f/2, ISO 200 using Pentax Q.

I’ve shot some videos as well, I’ll update this article after I finished edit the video.


Summary


Overall, Lumintop IYP265 is an excellent penlight for general everyday carry purpose. It can be stored inside your pocket, your bag, or any other locations where you use to keep your pen.


Powered by two AAA batteries which is available almost everywhere is a key point here and the use of Nichia 219B LED is a plus. It’s also looking good and elegant so you will want to carry it everywhere.


Pros:



  • Nicely designed penlight

  • Lightweight

  • Decent runtime & output

  • Using Nichia 219B LED


Cons:



  • I wish the mode sequence is L-M-H (personal preference)

Haha, I was expecting a blacklight and maybe a new led emitter based on that name.

hence the model name became easier to remember.

I have the light as well and i discovered that its not suited for me because i have it in my jeanspocket all the time and i unintentionally turn it on in my pockets all the time. That light would be great for the shirt pocket or jacket i think. As soon as you bend down to grab something on the ground it will go on, at least in my case. Others than that its a nice light for the money but i think the cree version would be better for me, i went for the nichia version and i dont know why but 120 lumens is a bit dim for me with the benefit of hindsight.

I just received this light, with the Nichia as well. Man, this light has got a nice finish; it’s got a nice silky feel. It’s a real shame there aren’t many lights out there with this 4000K 90+ CRI Nichia emitter (Jaxman I believe). It’s such a nice tint. I do think a golden clip would look better on this light than silver, but ah well… Overall my initial thoughts are very positive.

I just received mine yesterday, also Nichia. So far I really like it. I really wanted to try it with one 14500 and one dummy cell, but didn’t know how tight the input voltage tolerance is. Works fine on two AAA though. I like that it has that Nichia smooth even beam instead of a very bright hot spot and dimmer spill. I have a bunch of 3rd batch BLF 348s, and checked one side by side with the IYP 365. The BLF 348 is just a touch cooler than the IYP 365, but both are very acceptable. I actually like the tint around 4000-4500K best. Looking forward to EDCing it in my inner chest pocket in my winter coat. Won’t be long and it’ll be needed. Occasionally running the A/C last week, last night had to turn on a small heater as temp dropped to 40° F last night. I guess it is October.

Looks like I am going to have to break down and buy some AAA NiMH cells. My stash of alkaline AAAs is almost empty which is good. What are some recommendations for good AAA NiMH cells?

PS: I really didn’t need this light, but when one of you talked about the great deal you got on the Lumintop Tool Copper I went to check it out. Couldn’t find the deal, but got sucked into this one instead. You know how it is – you get over the hump about buying another light, so you are primed even if it is something you really don’t need.

My IYP365 replaced a 2xAAA first gen Preon in my computer bag. Death to cool white tints! I do wish it came on in low instead of medium though.

I didn’t remember that there were three modes when I started using it. Since it comes on in Medium, then goes to Low, I just assumed there were two modes. It was when I read this review that I realized there were three modes. Facepalm

So, to go back to my post from long, long ago, has anyone tried a single 10440 and a dummy cell? I’m guessing if one could find a 10440 in LiFeS04 it might be okay, depending on how tight the driver tolerances are, but regular 10440s would just be too much at 30% over voltage fresh off the charger.
