Thanks for answering. Sounds like a good plan. I was almost sure the centre LED doesn’t make a nice beam under the Cute-3, but as a kind of stand-by indicator it wouldn’t bother me too much. But adressing that LED when the main LEDs are off in a clicky light is something I haven’t seen anyone realizing yet. Thought about sacrificing one of the three triple pads for a red LED for some useful red modes as well, might try that in the next days.
they fit xp-sized stars (xp-e/xp-g/xp-l), and there’s threads and videos about how to reflow. i’m using a small gas torch to heat the stars, and so far i’m happy with the results
I put them into the light in post #169 in THIS thread and the body color matches the tint! LOL they are warm, but a very nice warm. Great LEDs at a spectacular price… Buy some for exploring the warm tints, very nice light out of them….
today i used a couple nichia-modded flashlights; my trustfire 3t6 modded to 3x dual nichias (a total of 6 leds), with matte tape on the glass to get rid of the donuts.
i also used my cheap boruit headlamp with xm-l + 2x xp-, where i replaced the xp- with nichias.
So: old leds and an old thread, they still can be useful!
Like microsurgery when it was swapped in one of my BLF348’s…. I really like it more than the 5000K… Very nice in total darkness as it doesn’t hurt my night vision as much… Less output, but still plenty of light…
Mmm, this has somewhat piqued my interest on these again.
With a driver like this 3-4x3 W Watt High Power LED Light lamp Driver Power Supply 85-265V 600mA, 3 of these emitters on alu stars mounted on 40×40×11mm heatsinks would make for a nice ≈350 lumens bedroom light. Of course, I'd have to attach all of that stuff to some sort of light fixture…
I hate the glare of overhead lights, so have a MR12-ish LED light mounted in a “flowerpot” bulb-socket + cord + inline-switch aimed at the ceiling to give a nice mellow diffuse ceiling-bounce effect.
Could just mount the critters in series on an Al block/strip, use a 12V wall-wart instead, and you can stick a suitable resistor in series with it. Eg, if 3V per LED (@700mA), that’s 9V, from 12V, leaves 3V headroom. For 0.7A, R = 3V/0.7A ~ 4.2Ω. Salt’n’pepper to taste. (3.9Ω would probably be the closest standard value.)
Mmm, no overhead fixture I was thinking on. Just a single E14 socket corded desktop lamp I have lying around.
Of course, the leds would be driven in series. That's how the driver I linked would handle them.
I was thinking in setting up the heatsinks around the lamp's tube in a triangular shape, for all-around light distribution. Maybe some cheap PMMA plano-convex lenses attached with hot glue over the emitters would also do nice…
I have a few of these coming from fasttech, figured I could toss them in some cheap hosts to replace the LB emitters they came with, can’t be worse then that I figure. From extreme blue to extreme yellow lol.
I would say that they would be quite a bit better than “can’t be worse”. I really like the tint these emitters produce, super warm and golden, very pleasant to the eye.
