LED Architectural with ECHO

Hello all,

I'm in the process of putting together an ECHO system for a church that I volunteer at that ties both stage lighting and house lighting together. The main sticking point that I'm having right now is specifying an architectural LED fixture that will dim down to a true zero smoothly. The plan is to use the 0-10v relay for each zone of houselights and I know that the main sticking point is the driver within the fixture.

My basic question is whether anyone has found a driver and possibly a complete fixture that works well to fully and smoothly dim to zero like most incandescent fixtures can. Almost everything LED seems to dim to 10% and then pop off. The ceilings for the space in question are fairly low (8-12') so I would need something with a pretty wide (90-110º) throw and we're shooting for a 3000K color temp with a CRI of 80 or above.

Any help or direction would be much appreciated.


  • Since this is an ETC forum it would be poor form not to mention Arcsystem. https://www.etcconnect.com/Products/Lighting-Fixtures/ArcSystem/  I've used them and they dim as well as anything on the market. (remember that incandescents have their own pop-on issues)

    I've found that DMX drivers (optional on many standard fixtures) give the best dimming function. In  Some 0-10V drivers are listed as "fade to black" but they are harder to find. The main tip I can give you is to talk to the big names Acuity/Lithonia, Eaton/Cooper/Halo, Lightolier, Hubbell/Columbia/Prescolite (off the top of my head) and get recommendations from your local reps. 

    The other method is to find a local architectural lighting designer. Someone that can look at the space and make specific recommendations and even drawings/designs. I know it sounds like an extra expense, but it will save money in the long run by avoiding mistakes and getting better end results. Would you trust a architectural guy to do stage lights? The reverse logic may apply. Regardless I believe it's money well spent, as I do this work regularly.
