there be a lot go on within the technology of flashlight recently . LED , Lithium battery , focus bezel , etc. . the Mag Instrument RX1019 Heavy-Duty Rechargeable Flashlight System be a ok rechargeable flashlight . but the technology today -lrb- ie from SureFire and other -rrb- have Mag Lights fall behind a bit technologically . for example , weight and size . if you be in law enforcement and need and depend on escalate use of force -lrb- ie loud assure voice , large heavy flashlight , side arm , shot gun -rrb- , most other situation only criterion for a good flashlight be how much light it put out and the quality -lrb- no dead spot , etc -rrb- of that light . and in the smallest , lightest package . this be where -lrb- in GENERAL -rrb- MagLite have drop off . I must say -lrb- before I get a bunch of negative vote -rrb- that I have own 20 or 30 mag over my work career . and the product be very durable and they be prove reliable . but for the money , I have find that surefire offer a more powerful beam of light . Surefire be lighter too . I have have to depend on my MagLight many time but I have switch to SureFire . it be the 21st Century . John Row
