Where can I get something like this? Its for a 3.7V project.

If it were over 5 volt, i can attest the dimming 700ma buckpuck works fine. The spec sheet incorrectly states 7 volt min. But i go down to 6 volts daily, keeping in regulation. Another person told me they got down to five… now I have another light with a controller that I added the radio shack 25 ohm 3 watt rheostAt that worksgreat. I put between cells and controller. These cheap controllers arent cc, so dim fine, infinite controll and more efficient than pwm.
