I am glad to announce this project as an upgrade to my previous project http://laserpointerforums.com/f66/4800-lumen-project-69095.html I got a LED build sold so now its time to shift gears with the help of this newfound funding.. This one is going to be a BEAST :D --- The new new build will...

The aluminium plate acts as a heat sink. It does not even get war to touch. So either the heat does not conduct well enough or the problem is somewhere else. The battery is a 3.7V li-ion. I have another one of these diodes with a microdriver running of the same battery, so that is not the...

Hello. I have a problem with my aixiz driver: When i connect the driver to the battery, it powers the diode fine for like a second or so. After this the power drops significantly and goes very faint, i think it stops lasing? Soon after this it stops completely. If i wait a few seconds it works...

Is there some consensus over how overcurrenting a led affects it's lifespan (and brightness)? I have a resistor to choose for my led driver that defines the current, and the specification is 1.5-1.8A for the led. I have plenty of heatsinking so the led will run at ambient temperature. Should i...

Yeah it does not even get warm to touch with that heatsinking :P The SST90 seems to be really neat but the price is way too much. These current ones cost less than half an euro per W, including P&P, and have slightly better lumens/watt than sst90. The xm-l i could not find prices for, but i...

Benm: Yeah it is not a spotlight :D The LEDs produce a cone 140 degrees wide. Things: No, actually you can see the charging port in the second side picture. You can charge it while its in there or take it out for safe charging in a lipo safe bag. I installed the fingers screws on the lipo...

Finished for now. With this configuration it has ON/OFF/FLASH switch in front of the handle and 30/60W switch integrated in the handle. Currently the LEDs are running at ~1.25A when nominal current is 1.5 - 1.8A. I did not have suitable resistors to easily bump it higher, will fix it when i...

This big boi is coming along nicely.

I was thinking about something similar to this Streamlight Fire Box Flashlight Without Charger we have in the local shop at special price. It was only 10 euros so i thought i would give it a go. Whatever i choose it will be something that does not cost much.

The LEDs attached to an Intel cooler. Perfect size for a flashlight, ok for a baseball cap. Lets see where this project goes from here.. :)

Thanks you all :) Ok i will snap some pictures when i open it up the next time (probably when the battery needs to be replaced). I am scared every time i open and close it since the old plastic might break under the screws. Currently it is in mint condition, i want it to stay that way :P

Baseball Cap LED Light 3200 Lumen - YouTube Here you go :) The video really does no justice for the light, you can see about 100 meters in total darkness. The night shot image in OP illustrates this well. The house in that image is about 80 meters away, and you can see it clearly in the image...

Thanks you all :) Haloid95: It sure looks heavy, but once on your head you virtually forget you have any extra weight on your head. Its not that many hundred grams.

Today i received two 30W LEDs in the mail, so it is time to start testing and building :D I was thinking about doing a flashlight this time around, the last LED project i did (baseball cap light) had no focusing of the beam so it lit up only 100m or so. Do you know any places to buy good...

It was sold by aixiz lasers, so one would think they knew what they are doing.

What kind of work lights/flashlights do you have? I prefer worklights over flashlights since they leave my hands free to do stuff. I could not find any proper worklights, and the almost proper ones were insanely expensive. So i decided to make one myself. How hard can it be? ;) One ebay order...

I bought the exact same driver, and manage to get a good lasing for about 1 second. Then it goes all messed up, i thought i burned the diode. But trying again and again i can always get the one second of laser before it fails. Cannot help you there, i ended up buying another driver and diode...

About a year ago i started this project with my nintendo zapper gun. I bought a diode with some driver that i could not get to work properly. Now finally i decided to finish this project and ordered an aixiz module with a cashio diode and flexdrive, now things are working fine. I also...
