content: I wonder if one could see that thing from spaceBut I think I've seen a video some time ago in which some americans built a 3kW LED-Light. Don't know if it was as portable as yours though. So you might need to put a few more LEDs on there to claim the Guinnes World Record of brigtest Flashlight

content: Nice work. How much does it recoil?Dwarfs my "death ray" project, 360W/30K lumens, if I ever get around to finishing it. Already have the LEDs and mounting plate so I'm kind of obligated now

content: Maybe give it a waterproof housing, mount it on a rotatable and tilt-able base and mount it on top of and power it from an SUV. This will be a lot more practical than hand held, and the vehicle with this kind of light mounted on top of it will be very useful in exploring the wilderness or search & rescue missions.

HeheI think something like 360W would be more useful than mine, if you put some decent batteries on itMine got a 400W switch and it still puts out enough light for just about anything you would like, on that setting.I guess it would last 45 min to an hour then, but still heavy as ****.. Your 360W would probably be nicer to carry as wellGetter' done !If you make a test video / photos, I'd love to see itQuote from: epiflow on March 24, 2016, 04:57:43 pmThank you!Yeah, if just it lasted longer.. But I guess another Kg of batteries wouldn't make a difference for a well trained officerQuote from: technix on March 24, 2016, 05:07:00 pmYeah, think you are rightIt was just for the fun of it

content: I need one of these for night biking. People seem to think they need the biggest and brightest LED headlights mounted at the precise angle to shine into oncoming cyclists' eyes.Maybe they'll get the hint?

content: Well WW2 searchlights were quite a bit brighter for a couple of reasons1) they used carbon arc light sources of about 15kW nominal power (ok efficacy is 3 or 4% lower but still it's 10X the power2) they used reflectors to get higly focused beamsStill that is a good toy

content: Looking at the build videos I am wanting you to use a countersink and countersink capscrews in places. Leaves a flat surface. As well in aluminium you can get a rolling tap, which forms the threads by compressing the soft alloy, making the thread by deformation which is stronger as you do not remove material but instead compress it and at the same time work harden it to leave a stronger thread. Larger drill hole but a nicer thread. But those spiral taps are great, especially as you can use a power driver to run them in thin through hole tapping, doing the tap in under a second. slow speed on the reverse though, you only want a single thread, and they do cut in reverse.Tip for next build drill clearance holes 0.1mm larger, helps for a looser tolerance on alignment.
