I purchased 4 100 Watt pro comps for my light bar. It ooked great, they never let me down, that is, until the rust came in. On the box it guarentees to be "rust-free"
after hours on and off the phone with 4 wheel parts (who i bought them through) i got in touch with pro comp. apparently, "rust free" means for the first 90 days. You get what you pay for so watch out.
