Blacklight t12 lamps are 100 lumens each.
These LEDs are 2000 lumens each.

Looks like it won't work at all.
The wavelengths they output are not correct for our emulsion.

The blue is actually in our wave length, 350 to 420, and will actually work better wth blue dyed Diazo emulsions.

while they might "work", they will most certainly NOT work better than a UV fluorescent bulb which is mainly in the spectrum your looking for.
First off, they use multi-spectrum LED's, but the weaker powered ones are close to the UV spectrum (what you need), while the other 75% of the light is way outside what you need...that means more than 75% of the power output is wasted. These would be a complete waste of your money.
The spectrum chart from the website says it all. Only the small blue band, rated at 0.4 of peak power is use able, the rest is simply wasted power.
