LEDs
Well I ordered 4 different types of LEDs today .. should be ariving in 4 to 7 days and then I can play around and get some hard numbers to determen there usefullness.
the ones I got are 5 of the "blue" with a wave length peek of 430nm 5 of the "blue" with a wave length peek of 470nm 1 of the "white" high intensity and 1 of the "blue" with a wave length peek of 470nm high intensity so now I just need to work on a powersupply and resisters to give me the proper current and voltage for them.

Neat stuff. Whatcha going to light with them?

I am realy interested to see how much floressence that the 03 actinic LEDs will actualy bring out. so I will also be setting them up on my tank and taking pics.. who knows if they are powerfull enuf I might light my bottom tank or the refuge with them to do some actualy preformance tests.. at pennies a day for a few LED's it might be a cheep way of lighting sumps and such if the PAR is strong enuf. Or even to use as spot lights in a larger tank to enhance show piece corals. Steve |
One note for you steve is that an Led may work well but the reflector you use determines alot.
So what if anything are you going to use for a reflector? |

you might want to look at omrons site. they have a new dr led that comes with a reflector. it supposed to be very bright. blue is 470nm
http://www.omron.com/news/n_241202.html i was very interested in this idea. looks interesting. they also have a pdf file on the specs wavelengh,intensity,etc |
I coudent find this PDF with the intensity of them on it but if you have it bookmarked could you post the link.. the two high intensity ones I have ordered are about 5 time brighter than a standard LED so I doubt that the ones you are talking about are as brigth as them but who knows..
there is another types that in new that is way above evenything else I have seen in power but they are 15.00 each so it will be a month befor I get one or two of those to test. Steve |
Cool Steve,
I was just throwing out my observations with the bike flasher that I have at my store as a refrence. I didnt know they came in diffrent deg. beams. very cool! |
Check this out: http://www.led.net/datasheets/25mm_m..._med_index.htm
Anyone got the $ to give these a try? Would be neat if we made a canopy choked with LEDs to cover our tanks. Heck you can even do dawn/dusk and cloud similulations with some ingenius controls. |
