Rabidgerbil38 Posted April 20, 2011 Share Posted April 20, 2011 So I've been looking around for a little while now and google seems to be producing no results. Dose anyone know where I could find some 420nm 3W LED's? Link to comment
redfishsc Posted April 20, 2011 Share Posted April 20, 2011 $5 each at Satisled.com, but keep in mind that they don't produce as much of the spectacular effect that we enjoy from actinic fluorescent bulbs like you'd think. These are also 400-405nm, which is a bit lower than 420. I wouldn't know where to find the true 420's. http://www.satisled.com/3w-high-power-uv-p...405nm_p285.html Link to comment

You sure about that? I haven't seen any on there for a long time now, but I could be looking in the wrong section. Their menu system leaves much to be desired.. Link to comment
sammy113 Posted April 20, 2011 Share Posted April 20, 2011 nanotuners. nanotuners is not carrying them anymore. They ran out and never got them in stock again. Hopefully some day will be available again. I really love my 420's Link to comment

It was a big inspiration on my current build, have your corals been recovering well? Link to comment
evilc66 Posted April 20, 2011 Share Posted April 20, 2011 Beleive me, I'm still working on getting them back. It hasn't been easy. There is a large hole in the options between 400nm and 450nm. LEDs inside that range are very uncommon. Link to comment
OrphekUSA Posted April 20, 2011 Share Posted April 20, 2011 Were you looking for a light that has them? Our UV/TV diodes are 380-440nm, but unfortunately we don't sell them separately at this time. Link to comment

Mr. Microscope Posted April 20, 2011 Share Posted April 20, 2011 380-440nm? That's a pretty big range. Do they cover that whole spectrum, or are they pin pointed somewhere in btween from LED to LED (binning)? 380 is near unseeable, and 440 is almost at the RB range. Link to comment
OrphekUSA Posted April 20, 2011 Share Posted April 20, 2011 Spectrographs are in our sponsor forum Link to comment

Do they cover that whole spectrum, or are they pin pointed somewhere in btween from LED to LED (binning)? 380 is near unseeable, and 440 is almost at the RB range. LEDs don't have that wide of a spectral half width, unless they are using phosphors to modify the light, which these aren't. It's an LED with a 410nm dominant wavelength with maybe 10nm spectral half width at 50% (very typical range, and where every LED manufacturer measures from). That means the effective range is 400-420nm. They may be seeing trace readings (less than 1% of total output) at the extremes that they are claiming, but it's not worth taking into account anything below the 50% mark. Link to comment
Mr. Microscope Posted April 20, 2011 Share Posted April 20, 2011 Here's the spectral graph. Looks like it's peaking at about 400 and 450ish. Definitely not many counts at 420. 420 actually looks like the trough. I've also done the google search. The closest I've found were 5mm 420's. Not good enough for reefs. Link to comment
OrphekUSA Posted April 20, 2011 Share Posted April 20, 2011 That's the fixture spectrograph, so wavelengths are relatively compared. Here is the actual emitter spectrograph: The peak is at 410 with 50% output at 390 and 420 (so enough UVA for fluorescence, and enough true violet to be seen), and appears violet to our eyes (see banner image in my sig). The trough in our PR-25UV fixture spectrograph is 430nm. Link to comment
Rabidgerbil38 Posted May 12, 2011 Author Share Posted May 12, 2011 Sorry to raise this thread from the grave, but I recently ran across THIS by chance There not 3w but I'm thinking they might work if I get enough of them Link to comment
Pilg0re Posted May 12, 2011 Share Posted May 12, 2011 I'm eagerly awaiting the return of nanocustoms/tuners TV led *crosses fingers* Link to comment
Rabidgerbil38 Posted May 12, 2011 Author Share Posted May 12, 2011 This place has 3w 420nm (or so they say), but there in china, and theres a minimum order of 100 pc... not so good for me, maybe good for Evil though *hint* *hint* Link to comment
evilc66 Posted May 12, 2011 Share Posted May 12, 2011 I have a hard time trusting a company that lists a 420nm LED output in lumens. Should be measured in mW. Doesn't list a drive current either. Link to comment
Rabidgerbil38 Posted May 12, 2011 Author Share Posted May 12, 2011 yeah thats what the "so they say" was about lol, but in all seriousness I think I'm gonna get a couple 1W's n see how they do Link to comment

Milad LEDGroupBuy.com Posted August 27, 2011 Share Posted August 27, 2011 Let me help you guys out. We brought them in. 3W 420nm - 450-550mW http://www.ledgroupbuy.com/true-violet-led-420nm/ Link to comment
STlighting Posted August 17, 2014 Share Posted August 17, 2014 SatisLED's price drops a lot now, starts $1.99 http://www.satisled.com/3w-high-power-uv-purple-led-star-emitter-420nm_p1259.html Link to comment
