The Red Cross Blackout Buddy emergency light (link to confirmation of modification), so you can have a warm white auto-on power outage light. Takes 3 emitters, I think.
The Red Cross Clipray is similar, but instead of a power outage light, it is a handcrank one that can run either lights, or supposedly charge USB devices (slowly).
The Coghlans dynamo flashlight is a very small crank light with 2 emitters. It seems like a good kids flashlight if it can hold up.
Received the package of 100.
There will not be a proper review until next tuesday (I will have enough forum chat time but there will be no hands-on cave time possible).
Quick first impression of one random led from the package:
*plenty bright
*very pleasant tint to look at
*very smooth broad beam (60 degrees from specs seem correct)
*edge of the beam a bit warmer than the rest (found it not disturbing)
*at ~20mA, middle of hotspot: 3325K, duv ā0.0039, CRI=97.4, R9=88.
Many will be waiting for the review djozz. Thanks.
Any 7x emitter honeycomb arrangement host or flashlight out there for these? Hexagonal/honeycomb is the most dense arrangement, I wonder why it doesn't seems to be widely used.
My first LED swap which didnāt require solder. In fact I only used a screwdriver, wire cutters, and tweezers:
I recently ordered some batteries from Shockliās aliexpress store and they threw in some freebies with my order. One was this cheapo keychain light. It has a 5mm straw hat LED that is press to activate and has a tiny switch to ālockā it on.
I bent and trimmed the legs of my Yuji 95 CRI 3200K LED
We have light!
I just now am realizing it had 2 stacked CR2016 batteries so I am probably giving this thing way too much voltage? Maybe a 2032 battery would have been more appropriate, who knows. I guess if it dies iām out 55 centsā¦
