[SML] Par 38 90w incandescent bulbs

[Riter, Andrew]

Thanks Bruce

I tested a Canto Par 56 300w replacement version for the Canopy above stage (122 Narrow Par 56) 3 years ago.  Went with the ETC ARC system DMX dimmable units.  very happy with those.

Had to mix high output and regular output, and that limited my lamp choice (dim to warm would have been nice).  You don’t get that nice 22% warm glow with the LEDs.  Sigh.

I really don’t want to convert my house lights to a DMX unit (more addresses !!!!   and wire pull to each and every pot light  UGH)
But a good dimming screw in LED replacement isn’t there yet. . . .

I’ll look back at Canto.

[CAUTION: Non-UBC Email]

The CantoUSA product has worked well for us. We did a complete potlight swap-over in our 3,100 seater and are happy with the result (Strand CD-80, Strand C-series controllers).

We’re now testing A21 LEDs for fixtures with axially-mounted med. screw-base sockets (Satco & TCP brands) (Strand CD-80, Johnson Systems controllers). This is more of a battle - it seems we’re fighting manufacturing consistency w/ Satco (TCP has yet to arrive).

The curves have to change, even one incandescent on the circuit affects dimmer response, and they’ll never look exactly the same..

We replaced our 250W PAR38 lamps with Canto 90W LED, and they dim pretty well on our Strand/Entertainment Technologies IGBT raceway dimmers. Our reputation got us a few to test on the circuit before we bought the 36 we needed.

Hi everyone:

as the world moves forward with LED conversions, leaving older theatres who don't want LED house lights blinking on or off for every house on/off, it appears I need to source Par 38 90w INCANDESCENT or Halogen bulbs.

I'm told that Gescan, Guilevin and City ELEC can't / aren't supplying them anymore.
(I’m in Vancouver BC)

does anyone know who is still making them?
does anyone have a supplier for them?
(willing to try to convince UBC to ship them here)

I might need to buy a 5 year supply, so I can wait to get funding and installation for a constant power / DMX controllable house light. . . . .

Or failing finding a supply:
What is the best screw in, retro-fit LED Par 38 90w equivalent that dims on Strand CD-80 dimmers  (willing to look at buying new LED friendly modules, if that is what it takes).

Thanks.
