i want a 18650 battery be seen throw light for around 20 bucks. i bought a q5 14500 light a while ago and well the battery last maybe an hour on flashing(flashes twice a second). really want 2-3hours on sos and preferably with memory. i will pair with a flood light for cycling. had a p7, but it died after a year, and was thinking of getting a SST-50 to see the road and all.

narrowed the be seen light down to:
SKYRAY XPG-R4

or UniqueFire L2 Cree XPG-R5

sst-50

i just need a little push to pull the trigger. btw magic shine won't work wel for me. i leave my bike outside and don't want the light to be stolen. seems like a hassle straping down the light and the battery every time. a flashlight take all of 2 seconds to mount and dismount.
