    Thanks to (sorry I don’t remember who) brought those LED emergency lights to the meeting to give out.

    I believe he said they ran on 3.3V.  Just for information’s sake, they draw about 1 amp (!) at 3.3V and are very bright!

    Thanks again,

    73,

    I brought them in and I may have more in the future.

    They run on 3.6v and I think that you can run them up to 14.4v if you wire 4 of them in series.  I have not yet tried this.

    You can always use lower voltages to achieve higher lumens per watt.

    Thank you!  And thanks for the voltage info.  I remembered 3.3.  No doubt at 3.6 it uses a bit more current also.  So these are roughtly 3+ watts, but they sure have a lot of lumens!
