What would you do?

Bold move going to LED's in these numbers.

I believe you have an Ion to control ?.

Big question though.  Do you do one-off events that expect an incandescent hang of S4 elipsoidals, Pars and/or fresnels and if so,  how are you going to match colors and intensities across a whole lot of cues with an assortment of LED's ?.

As example, you get an event that wants the cyc in R80, R64 and R19.  With assorted cues changing the intensities of those colors.  

This is one stumbling block I have yet to overcome and have put off on one occasion, purchasing an LED cyc set.

If everything you do (or most) is all new and/or you have time to do a cue to cue and match, then sounds like LED's will work.   If not....

Good question Steve, but not a requirement for our venue. We're strictly community theatre and local arts groups, with the odd corporate rental. There's no real requirement to colour match touring riders.

We have a pair of Ions (and an Express 125 and an AVAB 211 sitting on a shelf if anybody wants to make an offer). I might need to do an output upgrade to the one in the auditorium, but likely not.

We still have a good inventory of tungsten fixtures in the venue, but we would be selling off or giving away to the local schools, all of our Altman EC-1's, 65Q's, and 75Q's, and some of our scrollers. We'd be moving our S4 PARs that were being used for tops, to the black box/rehearsal space to beef up it's inventory, then replacing most of the stage units with S4 Fresnels and LEDs.

I am trying to solve 2 problems at once. We have a fair number of inexperienced/intimidated volunteers who want to get into lighting but find the learning curve daunting, so getting to a stock plot that gives them an easy starting point would go a long way. Financially, if we can get our electricity peak below a certain point we can save about $1,000 per month on demand charges alone. I think we're close enough that we can get there in most months but it requires shedding some stage lighting load and the corresponding HVAC load during warm months.

Ottawa Hydro has offered to provide a small grant from the smartONenergy program but I am chasing the provincial regulator to revise that program, or offer something specific to theatre, much like they did in the '90s when we got our first batch of Source Fours to replace our Strand 2206s. Since our theatre's usage pattern is off-peak from the supplier's perspective, there is less incentive for them to provide grant money.

I Understand.

I would demo 2 D40 Vivid's side-by-side and do a color transition to determine if it's smooth enough to eliminate the need for separate fixtures (fresnels) as the "other" color.  I have a feeling that between the console and the fixtures the color fades will be smooth enough to eliminate the need for that extra wash.

As to sides ?.   Using what is essentially a wash unit for sides is risky, in my mind.  You do get a lot of beam control with the lenses, but without shutters you leave yourself open to flare on that occasional mid-stage painted scrim, or painted legs (parlor legs and borders for Nutcracker ?), or the rear projection screen with a chorus standing just downstage ?.  Maybe demo the Lustr+ and stick a barn door on it to see what it does, but be aware that usually with LED's all a B/D does is reduce intensity.  

Hard to beat the VividR for cyc lighting, but I've heard good things about the Chroma-Q Color Force units.  Not as good a lens set though, which are very good throughout the Seledor line.

The fresnels aren''t so much for the "other colour" but to provide the "white" that would then be tinted by the D40 Vivids. The fresnels also offer much better spill control than a D40 is going to provide, especially for box sets where the shutter cuts matter more.

We've still got the option of using our ERS inventory for the situations you've described where spill control matters.  I'm not expecting any LED wash fixture to be the ideal choice in that role, just like I wouldn't use a PAR.  It's a good thought to consider adding some ERS tips to our downstage and/or midstage electrics for that eventuality. For recital season we typically add in our ladders and hang a complement of ERS instruments to boost the side lighting and provide texturing.

The dance company that uses our venue for Nutcracker (is there any venue that doesn't have a Nutcracker?) has this canyon-like 16' high box set/periaktoi monstrosity that pretty much negates good side lighting, other than booms set right upstage the proscenium. If we add some LEDs I can likely sneak in some shins and waists where it might not have been possible before due to heat management issues. It might be a good reason to build the cyclorama from D40s or Vivid 21s so they could be retasked as booms.

Good conversation! Thanks!

Take a good look at your dimmers.

Do you have enough dimmers/circuits currently? More LEDs can mean more dimmers for conventionals. Will you need to convert some to real non-dims or hots?

IMHO - if you are set for dimmers go with a hybrid system. Otherwise think hard about the trade offs.
