UV LED Manufacturers

[bstumm]

I'm looking to develop a list of actual LED manufacturers in the UV range < 400nm. Primarily I am interested in 360 ~ 390nm range but realize others may be interested in other wavelengths.

I've read the LED Museum and done some googling so I'm aware of some of them.

Anyone been down this road already that can point me towards existing resources specific to LED components? I'm in need of thousands of LEDs as my "widgets" are around 400cm2 and require a total of 15 to 75 Watts of output power (40 - 200mW/cm2).

As a fellow geek hobbyist I'd be happy to help other hobbyists with wholesale pricing on small quantities once i set up some direct relationships.

What kind of format are you looking for? 5mm? Metal can? High power? Anything below 390nm gets very expensive, very quickly.

I'm in the design stages now so I'm open to any package style but thru-hole (dip inserted?) would be the preference as we have thru hole manufacturing capability in house but could deal with surface mounted devices as well.

I received a response from an inquiry this morning that I have a hard time believing... 120mW radiant power output at 365nm from a 5mm round emitter from Hero, could this be true??? Seems very high power output from that package style compared to competitor offerings. And driven at 20-30mA current??? Cost $6-10 based on (smaller) quantities.

the fox group inc has 350 and 360nm can and 5mm's, 200uW output at 30mA. Heard good things about that company, but I myself have not dealt with them.

power dissipation = 120mW
output power = 8mW

Prolight makes a 1watt / 200mW LED. 390-400nm I believe.

Thanks for the responses

couples notes I wanted to make, which mostly relate only to my project but might be helpful to others.

bshanahan14rulz mentioned a fox group LED with 200uW output at 30mA. 1000uW (microwatts) = 1mW (milliwatts). I need at minimum around 15mW (15000uW) per LED assuming 5mm package size, could go lower if LED size is smaller and require higher output if larger LED package size.

AndreasL mentions 120mW power dissipation and 8mW output. The page I linked to says 110mW power dissipation and 8mW/sr output. I still don't understand how to convert 8mW/sr to XmW/cm2, can anyone help with me understand steradians? And how to convert to mW/cm2?

@blasterman, I'll check out prolight. 390-400nm is a tad high for my application but maybe they have 380ish too. From what I've seen output power goes up with wavelength for most LEDs. 385 is often close to double the output power of 365nm.
