Very bad lamp, we do not recommend buying these lamps or brand. We bought 6 of these. Unpacking the lamps, 3 of them came with issues, including scratched lenses and inter parts being loose. These loose screws inside the lamp were vibrating and moving, causing a series of sounds and mal functions in the inter lamp. We had to send back and after a fixed set of lamps replacements, we experienced issues with the use of the prisma mode. After some use, the prisma motor inside the lamp temps to break, causing randomization of the beam and use of prismas, very unstable to use. We again send back because of this issue, and they consistently refused to fix, change the motor or replace the lamp. Super bad costumer service, we do not find any positive value in their products.
