A friend of mine was just asking me about some cheap static lighting for an open mic he does. I've used clamp worklights and colored bulbs before. Lowes has the clamp worklights for $7.63 and colored CFL bulbs for $5-6.
OTOH I've got some cheap Chinese stuff coming in - some more $20 10w 120 degree floods (yellow and RGB), a couple $15 100mw RG lasers, a couple $10 3w RGB rotating lights, and a $19 LED pinspot I'd like to set up as a followspot. All for dingy bar gigs - brightness not needed .
