Yes, look at post 18.
saw that but was unsure if used a mod or was factory….hence the question
So can someone confirm if it will safely use a 14500 out of the box or that I need would need to mod it to run 14500?
If it requires modding then what other options is there for a AA/14500 headlamp that you would recommend?
Mine works with a 14500. But the lowest mode is too bright with the lithium, so I’ve gone back to keeping an eneloop in it.
How’s the long term quality with these?
I’ve heard some lights just quit.
I have 2 of these, one Nichia and one Cree. The Nichia has worked with no issues for almost a year now. The cool white Cree I got around Christmas. I bought it to mod, but haven’t gotten around to it yet. I use the nichia frequently for night reading. I’ve been very impressed with the runtime off of one eneloop pro.
My Nichia version has been great. All this winter it’s been under my helmet lighting the bike lock under the bike lid, and then in beacon mode for the ride to the train station or bus stop. It’s had several months of EDC/bike winter usage with no issues yet. Just one anecdote.
Welp, I ordered one, so we’ll how I get on with it. I’ve been without a quality headlamp for a few years.
For anyone wondering about the E03H and whether or not it runs on 14500, I can say definitely that the Nichia 219C version I purchased new recently will NOT support 14500.
It seems to run on the 4-basic levels but just a short burst on Turbo or attempting to enter program mode will fry emitter. 
Nothing wrong with NiMH performance at all, quite nice as is, curiousity just killed the cat.
I have the E03H, and the E02. Is there an E02H? Or is that the same as the E02? I love both of these, they just exude quality! Enjoyed the review, thanks.
Yes I recently got both myself but you can also just buy the H on its own too.
Great little light,they have quickly become some of my most carried for sure!
Clearance Sale Now!! E02,E02H and E03H 50% OFF
Will there be any more E03H with the Nichia?
Since it’s clearance, I suspect not.
I just ordered a Cree E03H, since no Nichias are available at the clearance price, though they are available at full price from some vendors.
I have an E02 with Nichia, and prefer high CRI, but I’ll give the E03H Cree a try at this price.
Just curious. Has anybody had success in taking out the driver/led assembly out in one of these? I know I saw somewhere here in BLF somebody swapped 219b on his (or her?) E02 and it looks like its only the retaining ring holding it in place. I can’t get my retaining ring to budge though and its all mangled now. My needle nose pliers has nowhere left to grip.
Says here to use tape for friction. (WTS) Nichia 219B R9080 sw45k & 219C 5000k R9050 - #6 by AnhTran. I would guess that anything rubber would work as well?
I think that’s for the bezel that holds the lens which is tight but I managed to remove that. The tube is also tough to unscrew but I also managed that. It’s the retaining ring that holds the driver that I can’t seem to move. Thanks for the find though. I knew I saw it somewhere.
I ordered a discounted E03H with a 219C, they claim WW, and they are still available at 1/2 price. Got mine in today - it's pretty nice, but the filters are a bit of a pain - mine are tough to slide. All in all, a good deal though, nice quality. The headband is so-so. Feels tight but also feels like it's gonna drop to my nose.
The 219C wasn’t available for the E03H when I ordered a few days ago. I’d much rather have the 219C.
