Hello to everyone !
I'm trying to build a led beam, the same as moving heads on stage lights.
It's for a light art installation. This is my job, and you can have a look at collectif-coin.com
My first attempt is with a CFT-90-W, an aspheric lens from Optolife (A380 : diam=120mm, f=161.5mm), and a cheap condenser lens taken from a led pin spot.
I'd like to post a picture of a comparison test between the above beam and a Martin MH3 (with a philips 5r inside , but I can't ...
The results are not so good. I'm pretty sure I have to find the right first condenser lens, but I don't know which one could fit.
Somebody to help me ?
How can I throw a maximum of light to the 120mm lens ?
Thank you !
