Installed some 11" Ice fixtures in my church a while back, 3 of which are supposed to cover the stage back wall as washes. Using both Vertical and Horizontal diffusers (I think we have one 60 degree V and one 80 degree H) plus another diffusion gell to get the wall fairly evenly covered. Pretty soon after the install I noticed a streak of one color on the wall emiting from each of the 3 fixtures (3 streaks to be more precise). From the floor it appeared there was a gap between the edge of the lenses and the inside edge of the fixture, so just thought the lenses needed to be pushed over more.
Well finally got up there and it appears the lenses are about 3/8 to 1/2 inch narrower than the inside demension of the fixture, so depending on which color is on, the very outside edge led will not have a lense or lenses in front of it and will cause the streak on the wall. If I slide the lenses over to the other edge then a different color will show because a different color led is on that end.
Any suggestions here?
Also 3 was recommended by our rep to cover the wall but it really needs at least 4. Can't afford another one at this time so since we are using the max width horizontal lens, what happens when two horizontal lenses are combined - like a 60 and an 80 as an example? I don't have any to experiment with so don't want to order anything unless I know it might work. Of course another problem is more spread less output, so having to deal with that as well.
