Hi.
For a simple stand alone system for a bar band I'd still choose a traditional PAR56 fixture over Leds.
Leds are great for the most part. The problem is the cost.
For most of the Led fixtures, You can't replace the illumination components when those wear out (pretty soon on some makes/models).
I haven't seen a Led system that would satisfy my needs for the price I'd be willing to pay. Yet anyway

.

Sam
