Just a follow up on this. The movers finally came (slow boat) after about 3-4 weeks. All seem to be operating. They are small, have fairly narrow beams (wish they were wider), and pretty bright compared to my other crummy fill lights. They seem to move and dim ok. Just started programming so I'll know more later.
FWIW the $500 for the 6 lights was the tip of the iceberg. I needed another ethernet-dmx node, t tops (2) hanging clamps (6), wireless dmx xmit/rcv doodads (set of 3) and some dmx cables and terminators. That all cost nearly what the lights cost.
Expensive education but I expect I could sell most of it as a complete setup to some DJ and make most of it back.
