An even smarter feature utilizes a small photo-receptor built into the side of the Orb, just beside the USB charge port.
Holding the on-off button for a double-flash of the light letting you know you've activated the light sensor and now the Orb will only function in hybrid mode when it’s dark. It lights up for about 4 seconds, which can be a bit disconcerting if you're trying to get to sleep and it's dangling over your head but certainly enhances its 100hour battery life. .
So, UVPaqLite have come up with a new and improved version of the Orb, in the MSL, their Micro Safety Light. The MSL -Micro Safety Light - is a compact flashlight and safety device. It's the light you'll want everyone to own!
The MSL is pocket sized, being a slimline lozenge shaped, light, with a more prominent on-off button than that found on the Orb. The LED is being in two different options, a bright white (30000-35000k) version with a 2.3 hour run-time or a UV (400-410nm) version with a 2.6 hour run-time.
It again features a pulse mode, with a 2 second / 2 minutes mode, or a 2 second /15 minute mode. These have runtimes of 140-156hour and 1037-1172hour runtimes in white/UV respectively. (It runs for almost 6 full days on the faster "pulse mode".)
The portable design makes it easy to take anywhere. Ridiculously bright flashlight. It glows in the dark so it's easy to find. The MSL also is designed to attach to a very loud emergency whistle (reported to sing at 115 decibels) which is great for survival situations, natural disasters, crime prevention, or to ward off animals. It's much louder and less exhausting than yelling for help. And the pitch of this whistle can be heard over loud rescue equipment or ambient noises.
The UV emission wavelengths of that LED option is particularity good at exciting strontium aluminate and will be the one I hope to get once the project goes live.
Now, it's battery powered, rather than USB rechargable, which is a down-side, but the battery time is cheep, plentiful and given the long run-times I see this as a good investment. get onto it. Get one for you kids, your parents and your own keychain!
