So, fist it take my attention by the fact that it is in a price range of 20W projectors, but it has 150W. So, I bought 2 pcs.
PRO:
- very bright. One projector provides more light than 3 old 1000W halogen projector
- the cooling fun is quiet enough to not be observed in a hall of 1000 people
CONS:
- the thouing angle is fixed. You don't have the possibility to adjust it. But it is correct advertised
- the lateral flaps are painted in white glossy paint. They are useless. You can't limit the lateral light. So, you have to make your calculation about the spot size, considering the 40 degrees opening.
