Platinum 5r Beam Hotspot

Hello... Have you inspected the lamp? If not look at the lamp first.. The hot spot maybe due to
A blemish on the lamp sphere.

Hi,
Thanks for the reply. I purchased another bulb only to find the same exact thing.

Expensive test.

What now?

Just out of curiosity, but have you opened up the head and wiped down all the optics with a lint free cloth?

Hi!!
You know, I have. Just this weekend. I removed the blower and ducting (if you will) that holds some sort of lense, it looks fine. I look through the optics with my eyeball and it looks fine.

I shine a light from a flashlight in where the lamp goes and project the 'image' on the wall. I can get it to look OK, but a slight movement of the flashlight makes it look bad (duh).

I got to think another bad bulb, but both bulbs project the same exact image (or problem). Hard to believe a blemish is the same on both bulbs?

This is my first/only 5r. It has come a long way, this is the last remaining issue.

Anyone in San Diego area reading this wanna meet up and do some part / bulb swap testing? I'll buy the beer.

hi Eddie it is possible. ideally we would want you to check with another unit but since you only have one then you can always drive up to LA and we can take a look while you wait.. let me know.

Are you guys open weekends?
Can I arrange something with you guys?
Long way to drive but I'll do it.

Tried a third bulb; same thing. Maybe something with the bulb holder.

Please send me a private email for setting up a time/date.

What kind of beer should I bring?

Eddie, actually looking at your picture, you aren't trying to use these beam fixtures as a projection are you? The platinum beam 5R is an amazing aerial performer, the actual gobo output and image itself may not look good or crisp, but when in the air with fog or haze, it looks great!

but if you look at the gobo on a wall and from even 40-50 feet away there will always be a hotspot from the gobo. you can try the frost filter to enable a softer looks to the beam but this will never clear up completely due to the optical design and its intended use on this beam fixture.
Make sense?

Hi Eddie, regarding the Platinum "Beam" 5r. This fixture naturally has a hotspot. It is not intended to have a flat field as it is also not intended to work as a "Spot" fixture on a stage. The intention of this light is to produce a sharp "Beam" of light at 200 feet away.
Using the fixtures frost filter, you can open up the beam and get a great wash out of it. as a wash this frost filter eliminates the very tight hot spot.. but if you are using to project gobos.. the hot spot will always be there... and this is the case will all beam fixtures. Hope this helps.. If you are looking for a flat field on a gobo projector, consider the Platinum "Spot" 5r.

Totally makes sense. I could not find the projection distance in the manual. I unfortunately do not have 40 feet (maybe I do; still not enough) of test room to try it out on. These lights come with 11 different Gobos, too (which I don't have). Just not sure why they bother if you need 41+ feet.

I really wish I had one to compare it against. I'm will to make the hike up there, meet some people, too.
Let's do it.

200 feet away, no we're talking!!! The gobos are so tiny. How in the heck.....

Why gobos at all?

Let's get together and compare.

Thank you all.

Hi Eddie, again, its aerial beam effect.. think about shooting it into the sky.. you will never really see the gobo projected on any surface... yet what the gobos do is give shape to the beam of light as it shoots across the sky.

I think you are all right.
I'm going to consider this light done and list it. Next is a 5r Vizi..

Thank you for the help and input.
