The jetbeam is not 10440 rated. But have no problems using a 10440. Well except when you try to look serious, and the hi mode ruins it all because you cant help smiling. It's a serious flame thrower on hi, so use hi mode in short burst, 30 sek or so, or it will overheat.
Love how the xq-e hi led just disappear in the centering ring designed for a xp-g. It's a shame no one makes a stock aaa light with the xq-e hi. It's a fantastic led for small aaa lights. Tool ti xq-e hi 4000K vs tool ti xp-l hi 3200K. The domeless xp-l hi gives more or less the same beam as the stock xp-g. Difference in throw, is insane. So if you guys want a aaa with some reach, swap the led to a xq-e hi. It,s really no contest compared with other leds in therms of throw using those tiny aaa reflectors.
For even more throw i bought the old illumination L08. It pushes the nimh to it's limt and it uses a larger reflector, the same reflector as the aa version L10. Swapped the led with a xq-e hi and the beam becomes even more focsed. illumination L08 with xq-e hi vs tool ti with xq-e hi. Dont think it's possible to squeese more lux out of a aaa light using nimh.
All three.
