    Yes, CAT5 data cable supplying the feed to a 400W blacklight load at distances over 80ft would indeed need to be armoured. The volts drop you would encounter would exceed limitations. This is the OHM law not mine!
    If needed I can draw a picture?

    PC works great on armoured cable. Thanks for asking.

    Kinda disappointed in overall selection available to the public. It's like I have to buy a wedding DJ type equipment, or have to break the bank and invest heavily in Wildfire. Is this really that much of an untapped market for business' to be in, or is there not really that big of a calling for an 1000w cannon or wash for $500-$750?

    Well, I don't really consider a 400W UV cannon type fixture to be wedding DJ type material. In the size of most wedding rooms here, they'd be overkill, especially if they wanted to light the audience rather than 'something' specific. (as with lasers, people are often ignorant of the dangers of a 400W arc lamp at close range, visibile spectrum or not)
    As I said previously, it all depends on what you want to do with them. As most people want a wide wash, thats what is commonly available for cheap.
    The Wildfire units don't really pack any more punch (400W) than the cannon type fixtures, they just use a different lamp, so they can use better/more appropriate reflectors. They look essentially like a decent profile fixture, but UV. So they'll be brighter, because they have a more concentrated beam, plus, probably better optics/reflector.

    I suspect the reason why they're so expensive is because the market is small.

    I seem to remember reading a thread about UV in a theatre environment on blueroom forum, where there was a requirement for it to be shuttered on and off quickly too. Might be worth a search over there, but I seem to remember it simply involved a regular profile/spot fixture, with a special filter and an iris. However, go and price up what that might cost and compare it to a Wildfire, I suspect it won't be too different.

    BTW, you can get narrower throw cannons, so might be worth looking for them. The other thing with the regular 'DJ' cannons is that they are so wide, they project a donut of light, so pointing them directly at the target can sometimes be counterproductive.

    You are using Bonetti's defense against me, ah?

    I thought it fitting, considering the rocky terrain.

    I saw this earlier:

    http://www.thomann.de/gb/showtec_uv4...845f10f88c84e3

    No idea what they're like but its a 400W spot uv similar to the Wildfire for Euro 118 albeit the bulb is extra.

    Similar one in Varytec Brand for only Euro 78:

    http://www.thomann.de/gb/varytec_uv400.htm

    Neither is DMX able though.

    TBH I don't know if a UV strobe effect would be very effective anyway given that black light is invisible except on reflection. Have you seen this before or is it something you just want to try?

    Just found this site by accident, some very high power UV strobes here - right up to 2400 Watts:

    https://www.interlight.biz/products....ES&dispgroup=4

    Not sure what they fit though and you need to check eye and skin safety at those levels to ensure the UV is the skin safe type and the levels of UV are eye safe.

    Many UV bulbs are industrial not leisure designated.

    Al, the first 2 you linked to are the DJ cannons he was referring to and are not the same as the wildfire unit. They take a different lamp for a start although both say 400W. Keep up please

    Most discharge type lamps have a uv element present, only most fixtures have a filter on the output to get rid of it. This is why they usually have a warning about running with the case open. The wildfire and similar units simply filter the visible wavelengths.

    for main rooms these 400W cannons are not enough i use them mainly for waiting rows / halls

    also be sure to check that you get the correct 400W lamp in your enclosure.
    i ordered the correct ones but received the wrong one and after 5 minutes the blacklight glass exploded (not the white 400W bulb inside)
    luckily it was at the setup and not when there was a row waiting
