Beginner looking for advice

Hi! Want to start doing light shows & want some advice about projectors, I looked at dunkane and apollo overhead projectors but they are 2,000 lumens 3,000 & don’t know if thats high enough or if that is something that I can modify by buying parts. I looked into amazon but if there is a better website where I can find projectors that will be able to do a good visual at concerts would love to get some recs, thank u!!
