Lights received promptly and in good order but were a bit disappointed that we could not install and used them in the dimming capacity until we purchased and wired up to a separate 0-10V dimming control which is needed in addition to a normal on/off switch. We did hold off on installation while we made that 2nd purchase and once the dimmer control was received we were able to install and use the light as we anticipated - and it does operate just fine. Our only half negative comment is that it would be much better for consumer-type buyers like myself if the listing and advertising made it clear that "dimmable" can ONLY be achieved IF a separate special dimming device is purchased and that a standard 120V dimmer switch can NOT be employed. This information is kinda there in the recommended extras but the buyer has to search for it to become aware of necessity. Thank you.
