Donât know what brand it is, maybe you can identify it on BG. It is of remarkable quality. 9x2300K, 3x5600K, formerly UV. Like it very much. Sorry for the dust.
Ehh, just shoe-horn a single 7135 in there to limit the current. Assuming theyâre all in parallel, 350 mA / 12 = 29 mA per LED. Djozz says theyâre good to 100 mA, so that shouldnât be an issue. Thatâd give you 10 lumens each, total of 120 lumens.
might be able to be used as a contact board. Solder a small spring or nipple to the center pad (isolated or connected to something I have no idea), got the 2 electrically-connected pads on the side (for those âbeadâ type LEDs), and wire up something appropriately to use that to solder to the board with the 9 LEDs on it.
Of course, insulate appropriately with plastic sheet cut to fit, etc.
Thanks Unheard. I found that searching for â12 LEDs UV flashlightâ on AliExpress brought up many listings for that light (or one that looks just like it), including some in different colours (blue, silver, and red). Iâve already ordered a couple from different sellers to try out.
You have to watch out for the the cheaper 9 LED version thatâs in many of the listings - it looks just like the red one in my photos which is absolute rubbish.
As contactcr mentioned, some 3 x AAA lights will fit an 18650. Iâve even used a 21700 in one. However, Iâm happy with the 3 x AAA in a low power light like this.
Thanks pc_light, that description is excellent. I hadnât realised there was a lens over the optic - I assumed that because it was plastic it was a single piece like in the later production FW3A.
Thanks gchart
Yes, I got them from CRX, I forgot to mention that :person_facepalming:
The aqua blue one already arrived with the split ring âembeddedâ, while the orange one (that arrived during the OL Contest due to the theme I had in my light) didnât have that. So I picked 2 thin drills and added a split ring to hold it to the lanyard. Thatâs why they are so bulky in some parts :person_facepalming:
Solarforce!
Black L2P with T head. Luxeon V2 4000k
Blue L2P. LH351D 5000k 90cri with cut and polished lens. I did it first time with this led and I can say that this is the easiest led to cut to dome.
Both have âBiscottiâ 5A driver.
I think I used too long copper stripe for blue L2P because I had a serious problem to push it. I hope I wonât have to pull it out because I donât know how to do it.
I did this build before âBarkuti described a problem with âBiscottiâ driverâ:ăconvoyăS21E XHP50.3 HI available now - #2554 by Barkuti, and I didnât even notice it. But everything works.
You can use plastic tubing 18-18.5mm diameter or what will clear the I.D of the battery tube, that will only contact the base of the aluminum pill and just pound/press it outâŚ
Iâm going to get such a tube⌠Once I used to take it out using 18350 and 18650 batteries, but this one sits so tight that Iâm not going to risk it.
