What is the gaussian spectral range for 395 UV-A LED Light?

I require a UV-A LED of between 380-400nm at roughly 9w of power, do you have this? 

Based on the details provided, we would likely recommend the 395nm version of our realUV™ LED Strip Lights, which costs $35.00 for a one-meter reel. This product would require a separate 12V power supply of matching voltage and would have a total power requirement of 14.4W at 4.5W per foot.

You may also be interested in our 395nm realUV™ LED Flood Light, which has a per-unit cost of $65.00. One 395nm unit of the floodlight has a 20W power requirement and contains a built-in power supply. As such, this item would not require any additional hardware for operation. 

Say that I requested an LED with a wave of 390nm. That will be the peak wavelength correct? What is the gaussian spectral range for it? 

While we do not have any data that describes the spectral distribution using Gaussian terms, the following specifications may be helpful:

• Our peak wavelength specification range is +/- 5 nm. In other words, our 395 nm LED would be guaranteed to have an actual peak wavelength between 390 and 400 nm.
• The full-width half-max (FWHM) spec is approximately 12 nm wide
