This is probably as much about terminology as equipment, but here are the questions. 1. Are the terms tube extenders and tophats synonymous? 2. What is the difference between a tophat and a tophat with a 5 degree eyelash – and what is an eyelash on a tophat anyway 3. What is the difference between a tophat with a 10 degree flock and a 5 degree full 4. Please define flock and full (as it relates to lighting, as I am sure there are other meanings that we don’t what to get into ) 5. While we are on definitions – Anyone know what an Anderson Clamp is? Thanks for any and all answers.
