Found this led developed in denmark.

They cost roughly 1150 USD.

Feel free to ask any question you might have. I know a fair bit about optoelectronics and quite a lot about electronics in general, but the purpose of this thread is to crowd-source the search for good LEDs.Lol i wish i knew more about LEDs, the entire 1st page of this thread went miles over my head
I'm also looking for good information on LEDs. I've been happy with my HID setup, but I'm wondering if the LED technology has advanced enough to finally compete at the judges table. I know there are energy savings, but does the final product hold its own against HID? I'm looking forward to seeing your spreadsheet of different purpose LEDs, but I'm hoping you highlight the LEDs that are best for OUR purpose.Feel free to ask any question you might have.

I'm currently trying to organize the specs of many LEDs in a spreadsheet, so it's easier to choose which LEDs suits different purposes.
It takes a bit of time, due to incomplete datasheets. If for example they say the LED will deliver 100 lumen at 350 mA, but it's otherwise rated to 1500 mA, then I have to look at graphs and estimate the output at 700, 1000 and 1500 mA.I'm also looking for good information on LEDs.

Looks VERY good mate!Smokingrubber- I think panels with enough juice will hold their own. I think part of the problem is DIY panels are sometimes low power. Based on Rives recommendation, I built a 300W panel, and things have been lush and colas abound. Here's one 4 weeks after flower. Vegged and flower under LED:

Very nice, I will use that for the Cree LEDs. Thanks! Keep the info flowing
That spreadsheet has â name "Ledengin spectrum Tool"JMD, that spreadsheet would kick ass, especially if combined with radiometric output figures, efficiencies and maybe Inada/Tazawa "corrected" figures too! Check knnabinoides work, maybe it could work as a starting point.
My Bookmarks...I know there was an online tool for calculating umol values and combining different leds for visual spectrum charts. Too bad I have forgotten where I found it. Address was somethingsomething.co.jp if I remember correctly? Please post a link if you know it or find it!
I think Open Office is able to open it as well.I encourage to use another format, not all of us use m$ products. I dabbled with something too, would be cool to see if it can be implemented to your work. Cheers!
If you got LEDs you want added, just post the link to the datasheet here and I will add them.JMD, that is looking awesome. No probs opening it this time on my Mac. Very cool! How crazy helpful!
