Hard to know for sure, as watts is just a measure of how much electricity it sucks, not of how much UV it outputs. My unit uses a 1000 w metal halide intended for stadium lighting (where it would be enclosed in a fixture to filter out the harmful UV and just emit "white" light). Whereas this bulb looks to have a coating to block the "white" light and just emit the UV. It may, or may not, emit more UV per watt than my bulb. Perhaps someone here has direct experience with such a bulb.
That said, I get 25 second exposures with Saati PHU emulsion. If you aren't already using a polymer emulsion, that is the cheapest and easiest thing you can do to decrease exposure time. (Note, do no get Saati PHU2; it is twice as slow, so as to give super-fast LED units more exposure latitude.)
