Hi all,
I am researching replacements for my legacy Altman Satellite 1 followspots.
Throw: 80' to downstage center.

575HMI lamps can frost up with many hours of use. Not too hard to check if this has happened in these spots. Satellites are pretty punchy if everything is good.

Yes, fans are loud. I think that any spot of this intensity is going to have considerable fan noise.
Robert Juluats are much quieter than most at any comparable size.

Yes, LEDs do fade. They develop micro-cracks where the crystal is fused to the substrate as they thermally cycle. These start going dark. The hotter they are run, the faster these develop.
There is no magic pill with lighting.

ALL light sources fade with age!

Incandescents fastest, HID/HMI and fluorescents next then LEDs.
Yes, but the first three provide much easier options for remedying the fades than the fourth (although at a much higher frequency)

Ushio in throwing in another brand has followspots to look at in not otherwise mentioned. Personally as a fixture service person... I can't recommend. On a show site today doing a bench focus. But how better something else would be? I don't travel to the USITT or other type shows in seeing other lights. I know I can continue to make these fixtures work 30+ years since they were fabricated. I'll still keep them running, and I hear from Strong... they will also. Though a Lycian is so much more simple and easier to bench focus. RJ needs a whole new program of parts to stock, but in general are not bad - so far.

Tri-corn.... what is money verses time - verses what was the third factor as a goal for replacing or fixing the lights?

Hi all,
I am researching replacements for my legacy Altman Satellite 1 followspots.
Throw: 80' to downstage center.
Cost: < \$7,500 each.
FC: How bright is too bright? I used Lycian ZOT 12HPs in a different venue. They were awfully bright and we rarely used them at full intensity. Other than that, they performed fantastically.

Considerations:
Lycian ZOT 12HP
Lycian ZOT 7

Elation Pro FS 15R

Let me know your thoughts or recommendations. Thanks!

The only one above I would not recommend as a followspot is the Elation Pro FS 15R. It has nothing to due with Elation (I'm sure the fixture is high quality), but with the light source- The Platinum 15R lamp is a Mercury Vapor lamp. As such it will have a very green spectrum (The fill gas is pure mercury), and low CRI (MAXIMUM of 80-85). This is the absolute WORST choice you could make for a followspot in which you typically want 95+ CRI for skin tones on the performers. Okay, that's not true. Worst choice would be sodium vapor. 2nd worst choice. Stick with Xenon (99 CRI, but chance of flicker), HMI (95 CRI), or LED (CRI getting better by the day- however-- Phosphor degrades over time, so the reds will be the first to fade (if it is an RGB+ emitter) and the CRI will go down unless they fixture has Feedback software that regulates the output of the individual colors to keep CRI consistent over time, reducing overall output instead. A White LED (that uses color filters) might be a better option for a FS.

For what it's worth, we love our (relatively) new Lycian Mini Arcs. Probably not powerful enough for you but we downgraded from some Chinese junk that was waaaaay too bright for our venue and purchased by someone years ago who liked spending money for the hell of it. The mini arcs are cheap, tiny, easy to use/maintain and totally quiet, which was important for our open spot booths. Maybe not what you need, but I'd highly recommend these lil' guys for smaller venues especially like ours where we have brand new spot ops almost each production....
