An advertisement containing a questionable specification arrived in my Inbox this morning...
Emphasis added.These LED base units can use existing Source Four parts for easy retrofit. Save money on power bills and change color effortlessly!
-Only 265w per fixture at full!
-Use both standard AND zoom lenses with same LED base unit
-Project gobos and patterns
-Save $ on power bills, replacement lamps and color filters
-Supplied with pipe clamp, A size pattern holder, soft focus diffuser, and powercon to Edison power cord
1. Does anyone other than that particular vendor offer these magical "zoom lenses"?
2. Should someone explain to them the convention that adapters are always specified MALE END FIRST! ? A male Powercon to female Edison is fairly useless.
