Boruit Headlamp Review D10 (aka. EHL0628) - King of the Budget Headlamps?

Nice mod :sunglasses:
A better tint and beam as well!
I’m still using mine with the original LED, but with a pebbled TIR ! Maybe someday I get inspiration from you and swap a NW or WW tint LED !

Thanks for sharing!! :+1:

Ok, I have new lumen measurements after the emitted swap to the Nichia 219C. Numbers are down from the fake XM-L2 emitter measurements (which I guess makes sense). All taken @ 30 seconds

Level 1: 12.5
Level 2: 45
Level 3: 115
Level 4: 228
Level 5: 448

According to djozz’s Nichia 219C test (bin difference???), he measured about 675 lumens at 2.0A. That’s without any losses, so if we guess 20% loss 675 - 135 = 540 lumens. I wonder if I damaged the emitter during the reflow (took me a couple tries to get it on right).

finally got mine and i swapped it with 5200K tint + 90 degrees TIR optic lens, my most used headlamp right now :+1:

What are you using to measure the lumens?

Did you find a TIR that fits, or did you file one down?

Extensions leads are the way to go on this headlamp.

I tried soldering new leads onto the driver, but I’ve had to put the mod on hold until I get some thinner silicone insulated wire. Getting the wires into the channels in the battery compartment is a pain, and there’s no room for any slack at the driver end.

I had to file one to fit! I used a TIR lens like the ones used for Convoy S2+, but it didn’t fit well, so I filed it on the edges and it’s good now :wink:

My DIY foam ball integrating sphere, which is now calibrated against the average of 3 Fenix HL55’s. I don’t expect my numbers to be extremely accurate, but close enough and they are definitely consistent and repeatable.

Look closely at my 3rd pic in post#79 above. You can see the edge of the dome looks nicked. Output looks normal without any weird beam artifacts or weird tints, so I assumed it wasn’t anything serious. I do have one more Nichia 219C left and could try that one, but I kinda feel like leaving well enough alone.

Just a comment on the included Boruit “4000mAh” 18650:

Recently ordered some of the other Boruit headlamps for trying out, including the above EHL0628 (single “L2” LED) and another very similar headlamp but with dual “G2” LEDs. I ordered the package which include 18650s.

The Boruit “4000mAh” 18650s from the recent batch I ordered arrived last week and I did capacity test — these new batch Boruit 18650s now register only around 1200mAh capacity (0.50A discharge rate using MC3000, from 4.20v to 2.50v cut-off)

(I checked my previous Boruit 18650 with around 1600mAh capacity, which weighed around 39.3grams; whereas the new batch Boruit 18650s weighed around 37.0grams and around 1200mAh capacity)

Maybe their batteries are like Ultrafire?

Dang, I totally missed this headlamp because I thought it was about the other Boruit! The other model has worked great for me at work but is about the size of a RedBull can compared to this one.
Thanks for all the info and modding tips!!! Now I just need to find the best deal and patiently wait for round-the-world shipping.
I work in a production shop that is too broke to replace failing lighting and even with proper lighting it’s difficult to see inside machines for repair. I’ve turned my fellow employees on to headlamps and they now reach for them rather than trying to work on things one-handed with a standard flashlight. This type of safe, rechargeable, effective headlamp is a blessing.
BLF FTW!!

edit: JasonWW, WTH is that battery you posted?!!! unfreakingbelievable

It’s cheap at the official Boruit Aliexpress store.

Unno, I got a RJ02 (the “Red Bull can”?) and am quite happy with it.

But yeah, when I couldn’t find my ’02 and had to grubble around in some boxes, I was loathe to do so one-handy with a regular light, then remembered I had it hanging on the doorknob by the headband. :smiley:

So much better…

Sorry, exaggerated for clarity. “Mini energy drink can” is more like it.
The LVP, higher PWM frequency, and reduced size of this one is hard to beat.
Don’t use aliexpress much so I’m loading up the cart.

Aliexpress is like ebay. Many stores under a common payment system. So you can buy a lot from a single store and it should ship together. If you buy from a lot of different stores, they will come from different locations and take different shipping times. Some stores are more reputable than others.

In case you didn’t know.

Last time I ordered about 6 items and every one of them require a signature, so a trip to the post office very time. Will try to avoid that this time.
Any idea if there’s room for a magnet in the tailcap?
Wonder if repeated removal from holder will make it lose its grip.

What? Every one of my orders got delivered to my mailbox. I’ve never had to sign for anything from AliExpress.

I guess you could add a thin magnet in the tail cap as long as you use a short battery. Also, it may not screw on enough to cover the O-ring.

The headband holder is rigid plastic so it shouldn’t get soft over time.

(this is a repost, I was in the RJ-02 topic)
I have finally try the latest boruit
I was pretty convince the first day…

only work when charging now… don’t know why……
anyone ever had the same fail as me?
headlamp working only when charging?

light is back, it was in something like a “backpack lock”, put pretty unusual to undo (still don’t know how I’ve done…)
