Does anyone remember the deal with a solarforce extension tube, mentioned here:
I can’t find the topic.
The reason I’m searching for it is because I’m buying this p60 dropin, and want to do some research into what options there are for a host with possibilities for some decent battery time in it: http://www.customlites.com/P60-Led-Engin-365nm-UV-P60-CR-UV.htm
It’s a gift for my ol’ mum, who also sometimes goes amberhunting. But she has not got the amber fewer as bad as I do
With a single tube you can use 1 x 18650 or possibly 2 x 18350. With the extension tube you will need 2x 18650. Another alternative is using 2 primary CR123 with a single tube. Doubling up protected cells may be too long but I’m by no means certain of that.
Edit- no calculation is needed, it says in the link from the first post 4.2-8.4V which is one or two liion cells in series.
With your run-times, basically, 2*18650 is going to give almost twice the run-time of 1*18650, assuming the same current to the emitter.
Of course, the efficiency of the buck driver will play a part here.
With your voltage question, 3.7v is the nominal voltage. Fully charged, they are 4.2v (some cells are 4.35v). So you could potentially have up-to 8.7v with two fully charged cells in series.
Crap!
I just realized that customlites.com dont have the package with both l2 body and extender. I had to add both body and extender separately to the chart.
5.99$ plus 15.99$
Furthermore according to Dave, customlites are offering the 2014 models, whereas solarforceflashlight-sales.com are selling 2009 and 2011 models (at least for the models I bought)
Looking forward to see if I can get a sunburn from the Ledengin z1 8)
