Replacing Halogen Bulbs with LED Bulbs

Our maintenance staff want to replace all of the halogen bulbs in our auditorium can lights with LED bulbs. We have the house lights on the same Sensor racks as our theatrical lighting and we control it all with the Paradigm system and an ETC ION control board.

Can they work well? Do you recommend a certain brand or style? Are there any risk to the dimmers themselves?

The LED's do say dimmable but I know we would have to work on the dimming curves to get the most out of them.

Any help would be appreciated

  • This is happening to me too; slightly different system though so take my results with a grain of salt, test for yourself. 

    Sensor Racks, ETCNet2 & sACN both control via Cobalt-on-Congo and Legacy Unison. The  http://www.tcpi.com/spec-sheets/ELITE/Designer-Elite/Designer-Elite-DIM-PAR-Series_print.pdf is what we liked* in a PAR38 size, and my local tech support guy allows as how it's one of the least horrible options he's seen. (He estimates his clients getting this kind of request a couple of times a month, these days.) The fade got down to about 6% before dropping out: if they pull the trigger on this purchase I'll try to create a custom curve for them from the desk. No perceptible flicker, and we tested without the existing diffuser lenses in place. However: we did see them briefly stick on at the bottom of a 5-second fade, couldn't duplicate it, but it does indicate caution. The whole circuit behaved as one, no popcorning within the bank of 12, but I wouldn't want to rely on the idea the whole roomful wouldn't do the same thing unpredictably and probably not in unison. In concert. Simultaneously. 

    *By "liked," honestly, what I mean is "was surprised to not completely hate."  Building a fade that is more immediately perceptible to the audience--steeper at the top, I think--will be a challenge. I'll fling an email at the pros for more input, but my only other concern right now is the potential for camera flicker in casual video shots. If we light the audience specifically for IMAG, I'm sure we'll put tungstens on them, but I'm not sure without that there might not be a problem.  Hope it helps.
