(Note: They are straight off the hotplate, cooling down. Haven’t been cleaned yet! )
4 orange unknown emitters for a “lantern/bonfire simulator” project.
4 219C 5000K to a PL47 board.
And took off 4 XP-L HD (1 broken) emitters, and put on 4 SST-20 4000K
Given my recent journey into reflowing, it has accumulated a lot of loose emitters.
How do you store your bare emitters ?
If I think I will use them again I put them in a small ziplockbag with a label on it, but most end up loose in a boring-parts-box, usually to never be used again. But occasionally I take one out for a build and nowadays I can check tint/CRI before using it.
Not my mod but attention worthy:
Vinh has upped the power of a LEP flashlight, increasing output by about 60%. He may be the first to do so and speak up publicly. Click
One is a mountain electronics 10mm FET I never got around to using. One is some performer made by a blf member I cant remember. The driver was a big deal at the time I purchased it so maybe chops can post a picture of it and someone will recognize it. The package it came in came from Croatia.
Yep that is it. Looks like I have an old version but it should be a 12 amp capable driver. For sale : LD-2 and LD-M2 driver (Updated) All my comments when ordering are here.
It runs on a single AA and has a small 3mm led that lights via a momentary switch on the back, to check the time at night.
It is pretty bright, my planned mod was to add a high value resistor in series with the led and replace the momentary switch with a slide-switch, so the clock can be lighted all night at a non-disturbing brightness. I like that much better.
I was surprised to like the tint of the led, pretty good for a cheap travel clock, so before starting the mod I checked the tint with the spectrometer.
And good it was indeed: 2300K, 96.3CRI, R9=83, duv –0.022. This is a holy grail led , where did the Hema source it?
I would love to see some new leds with round die. But for now i am really happy to have my SBT-70 Aspheric on my shelf. Again thanks to DB Custom for making it possible.
Had to mill the underside of the led cover thinner to make space for the SBT-70. The cover barely touches the glass above the led. Took some time to center it but i think now it looks good.
Before the assembly every part was really good cleand and i still have a few dust spots under the lens .
I would love to add some shots from this led in moon mode. The blue shining line arround the led looks so cool. But with my phone it is not visible. Maybe i can find someone in my area to take a few nice shots.
