Some tuning of cheap Biltema flashlight...
- 50 W 24 V 4000 lumen LED from Dealextreme
- tiny cooling fan
- 2x 12V 1,2 Ah lead acid batteries
- Switch for parallel/series (series in use and parallel for 12 V charger)
- DC-connector for charger
- 555-timer circuit for epileptic strobe effects :D (Adjustable flash speed with potentiometer, pulsewidth trimmer onboard)

08.02.2013 00:05 NiBaI have some car repairing to do so other projects has been a bit frozen.. This flashlight has been a great tool on the repairing.

20.01.2013 15:48 alfonsIs there constant current driver for that led? Is there really a fan, I cant see one.. because that cooler propably needs one. And where are the in-use photos?!
21.12.2012 23:55 NiBaYep! I'm going to shoot some in-use photos some day. :>
28.11.2012 10:33 Ozzkuu:D Nice one, want to see some in-use photos too!
27.11.2012 20:56 JipaThe battery is pretty damn ghetto :D Other than that, why not - using a factory made housing sure makes sense..
