Yes. Use the relative brightness product of response to calculate individual wavelengths of light using average human reponse so that equal colours are mixed into a single beam. Its probably best done with some optics, such as dicroics and mirrors, although I have never actually built one...

With the same power in terms of milliwatts, a 532nm source of light will be 192 times brighter than a 405nm source of light, given the same power. Sam's Laser FAQ - Items of Interest

Simply just wait. I don't like their new ordering system. They don't really provide you with tracking, do they? March and April have been a disaster for shipping. It took them 2 weeks to package them... If they don't ship within 2 months, you should probably buy your batteries from a different...

Haven't posted in a while. Goin' back here now... I've always seen how 'psychologically advantageous' they are to younger folk, and its so obscene in my opinion, as its strongly appeals to 'tech'... but thats the way the market works. Can't do anything but to complain... :D Those deplorable...

Stay safe. Wear eye protection and all. I have failed many times doing this stuff... on a moratorium of spending, heh.

Ahh, don't worry. China takes a while to ship. Consider arranging a flight from China to the USA. All the way around the world for a low price of shipping... not to mention sometimes free. If you like to check often, check every 1-2 days at 4-5pm, because they scan usually at 2pm and it takes a...

I always knew about that... thinking about thermal capacities... but yeah. I understand. Do you want me to include that in the OP?

Glad to see WL's rep dropping like bird waste. Don't forget it could be an internal issue... it could be the bulb OR the driver thats controlling the current that flows into the bulb. Just to float that idea out there.

You could try the Boostdrive, by the same guy who designed the flexdrive. http://hacylon.case.edu/ebay/laser_diode/Micro_BoostDrive.php If you don't know already, thats his website. There you can buy the drivers directly form him. Its roughly the same size. I like it better because the solder...

Furthermore, this thread is in the wrong forum. Please ensure that you are in the correct forum. This will be helpful to other people. It should be in the Batteries, Drivers, and Testloads section. Feels like an advertisement? IDK, but thats my opinion.

Since this is my 1, 2, 3, 4, FIFTH diode that i broke... 3 of which were PHR's and two of them were 445s :undecided: I decided once again to share not only the experiences, but my knowledge as well. Here are the things I learned after breaking FIVE diodes, in the order I learned them in. Now...

I used a boostdrive from lava. It shorted when I didnt know the wires got twisted when I screwed the upper module of a C6 flashlight... turned it on and a 2 sec. blast of blue appeared, but died almost immediately...

Thanks for the rather rapid response DTR. This diode was ONE of your diodes you shipped out recently. Anyways, what is the resistance on a functioning 445 M140 diode ?

Well, once again with my amateur skills, I managed to get everything right until the wires twisted and shorted itself out. Shoulda used heatshrink wrap. Everything right until the last part. Since the short happened AFTER the driver, should I expect any damage? And how can I ensure myself that a...

You can probably ask one of the forum members here to produce such a heatsink that you must require. Typically, people here like to use cylindrical heatsinks because they can put it in flashlights and so forth. As for the material, you have two options. Low price and high price. Aluminum is...
