The LIGHTCANON - [flashlight]

[thekeemo]

Here is a (somewhat) strange question

How well would this light up a room?

all u need now is a batman logo cutout and ur set

its like, a very intense point of light, so if you point it at something white like a ceiling then it lights up the room pretty dim

So basically a lamp on roids

its not as bright as a lamp though, theres only like 500lm coming out of this thing

Do you know of a video or have one that I could watch to know how to make one of those?

How to make this flashlight?
I have all the build log videos on my youtube channel, link on my profile

Quick lil update

 

So I made some modifications including gluing the temp sensor to the heatsink using arctic silver thermal adhesive for more accurate readings.

 

I also removed the LED driver and connected the LED directly for "direct-drive" maximum power

This means the LED will draw current depending on the battery voltage

If you follow the light gray line, the current going through the LED at 4v is about 6 amps, but the resistance of the wires and switch in my flashlight probably reduce that a little

so the amount of power I'm getting is slightly more than with the cheap chinese LED driver

 

I just did a second test with my light meter and got about 37000 lux at 5.3m which is 1M lux at 1m

So this flashlight is capable of doing 1M lux, just without the driver restricting it!

 

 

SUCCESS!

Anyway, now I'm just looking for small things to improve, such as neater wiring and things like that.

 

PS. I have discovered a new type of lens called "catadioptric" and advertises a ultra-narrow beam angle of less than 2 degrees http://www.carclo-optics.com/optic-10158?beamangle=1%20to%2010%20degrees

This seems a bit wider than what my lightcannon can do (although i havent measured beam angle of the lightcannon)

But it may be a lot more light efficient, possibly making up for the extra spread, and possibly making a much more powerful flashlight in the near future

This thread is dead, but I love this thing. Planning on building one soon :3 Any updates after nearly a year, OP?

Haha thanks  I still have to do the 1400m test, I'm just really lazy to go out late at night.

Currently working on other projects not flashlight related, but I have some good idea for my next flashlight builds.

I'll make sure to post an update in this thread when I begin another flashlight so be sure to follow

I really enjoyed this post, I'm amazed there is enthusiasts making their own $400+ flashlights. Have you had a chance to take more pictures ?

Not yet, but it's getting darker out now and closer to winter so it might be easier for me to do the 1400m test sometime soon.

I also have parts ready for a new type of flashlight, so follow the post for a notification when I start building it

Hey everyone!

I have made some modifications to the light to increase performance!

 

Some time ago I removed the cheap V10+ driver and ran the LED in direct drive off of a lipo battery, but with 4.2V the LED was only drawing ~3-4 amps, so I decided to spend $20 on a good quality constant-current driver from MTN electronics, which runs off a 3s battery and provides as much voltage as necessary to achieve 6 amps to the LED. http://www.international.mtnelectronics.com/index.php?route=product/product&path=67_115&product_id=691

Now the LED is running at full power, and I have taken some beamshots in the mountains

 

First test, 950m to the top of a mountain, the target is a radio antenna.

 

 

 

 

Zooming in you can see the antenna is well lit up, even though it is a bit blurry because of my camera  The red dot is the signal light at the top of the left antenna.

 

 

 

 

Second test, 300m to a nearby mountain, target is a large metal cross.

 

 

Just below the cross:

 

Hope you guys enjoyed

nice update i did enjoy it

Search for "lightcanon flashlight" and it's the first result

 

 

 

Also, now that people will read this topic again (luckily necros are allowed in the build log subforum!), I have recently built the second version of this flashlight.

Build log on a separate flashlight forum, check it out if you want: http://budgetlightforum.com/node/55370

4.63 million candela, over 3x more powerful than the LightCanon, and the current world record for aspheric LED flashlight  

 

Maybe I should also post it on LTT if people are interested?
