I just got it, following the advice of some forum members to have a bit more deep blue!

This gives good things compared to a Par 56 and PAR 64 (500w).

I think having tried with several gelatine, it gives me almost as much light with a 575W Source Four Junior has a very good perspective!

Then of course one side is a cutout of the other PAR 600w with 4 lenses.

So then I'll see what we get during the month of June, 10/12 show planned.
But between the price of PAR, under 70 € and the bulb, 18/20 € for 1500h, and therefore the 4 lenses and the other a par 64, 20 €, the bulb 300 hours between 16 to 22 € I finally found that the multiparty seems more interesting. Compact spare bulbs, projector smaller and more compact, gelatine in 19.5, I think I'll try to make a small park multiparous!
update

So I could use it not for the blue on the last show, but I actually tested the bottom of room for catch-up face with a gelatin amber, (I think 152) And done that was positive. Well obviously we can not settle the edge of the beam on the proscenium unlike a PC, but a single projector was doing no harm ...

So now we're going to see blue in the next show. Now I have 4 PAR 600w, 2 and 2 Showtec Elation.
