Thank you for the link. That is exactly what I was looking for, and I will get a couple of these for sure. They are very well priced too, and I can dim the led's!
Just as a comparison I may set up and automated test with the step up converter and the meanwell and run them for a few weeks side by side just to see what the effect is with the different setups.
Thanks,

Re: Bridgelux 1100 lumen High Power LED's
I dont know you've understand that the Meanwell are not a step-Up. You need to power it with min 22V. So you need the converter AND the Meanwell. With other LEDs the converter is unnecessary!
Re: Bridgelux 1100 lumen High Power LED's
I am actually going to run 48v from my tether into the meanwell before 48v is converted to 12v for thrusters. The meanwell is a step down so it will work ok.

Re: Bridgelux 1100 lumen High Power LED's
Hey Guys! I have been following this with quite a bit of interest, and I think I have a configuration setup that fits the description. I have not bought these parts yet, but wanted to throw this configuration out there... see if I've got this right:
Battery (3cell Li-po) --->DC/DC Step up set to 24vdc Out --->MW LED Driver LDD-500H ---> LED.
Requires 21Vdc @ 500mA
Input 24vDC Output 21Vdc @500mA
Input 11-12Vdc
Output 24vDC
Alternate DC-DC step-up
Thoughts?
DC-DC Step-up $5.18+$7.35(shipping)=$12.53
Driver $9.96 + $6.99(Shipping) = $16.95
LED $7.71 + ?
Total: $37.19

UPDATE!
Now that I have found a local Maker/Hacker Space with some proper tools, I have had a chance to test the LEDs with the MeanWell Drivers, and I can confirm that it works PERFECTLY! I even have the dimming circuit working via some very simple Arduino Code.
At this time, I am just running it all from a 24VDC bench top power supply. I have not tested the DC-DC transformers. That is next week!

Hi Kr2_diving,
The movie is set to private so not viewable for us. Was wondering if you thought about using a mirror, that will focus your beam and thuse increassing your amount of light in the area you need it.

Oops! All fixed! Thanks.fryslan76 wrote: The movie is set to private so not viewable for us.

P.S. This sucker is so bright... that focusing it with mirrors might just create a fish death ray... hmmm... come to think of it...

Hey Ryan,
How hot do those things get? Are you gonna need a heat sink in whatever enclosure you end up using for them?

In a word... hot. Yes, the housing I am planning on building will double as a heat sink. For testing, I do have it mounted onto a piece of aluminum bar stock with blue tack. You can feel the heat come off the diodes when it is on, so I am sure it will burn quite hot when it is on.odics wrote:Hey Ryan,
