Well nuts…I had no idea they would put in this type of emitter. If I had known that I don’t think I would have ordered the light. Figured we’d be using a normal/standard die and footprint. Oh well, at least it was cheap and maybe it’ll be fun or make a good gift. Unless that color temp is exceptionally nice it probably won’t be a keeper for me. Not sure I’m too keen on sourcing some of those emitters to swap but I guess that’s an option.
Pretty radical departure from the norm…would have been nice to have that communicated.
I just got a word with Clemence (ERKX), showed him the emitter datasheet and he said it could be a straight Nichia E21A swap. Not 100% sure because i don't have it on hands but soon (hopefully) i'll report back with some mod update. :)
Man these emitters are skinny! If you’re going to mod, get out your super fine hair tip tweezers. Data sheet isn’t all that encouraging, compared to emitters we are used to using. The reflow characteristics hint at users being able to do it right and do it quickly, and be able to control the temperature decently.
Specs say a total thickness of +/- 0.32mm. That’s including the phosphor. That’s about one half of a B35AM and those are pretty thin! For the SAE among us, that’s about 0.013”, thirteen thou….1/64” is about 0.015”. Looks like the base is something around half the thickness (phosphor being the other half). Sounds easy to damage the edges/surface of these with typical small electronics tweezers. Also seems like a candidate for using a stencil with solder paste…those pads are teeny tiny.
So my house was robbed last week and they took my KR4…I came on here looking to find a reasonable replacement and sure enough, here it is…but it looks like I missed out on the Orange one. Any ETA on a new batch?
I can solder very well, what size are the aux LEDs?
Orange with a battery seems to be in stock still. Orange without a battery is out of stock along with both options with ice blue aux. Even if you don’t need the battery, it’s only 2 bucks.
