Conventional Fixtures ETC Source Four mini - brightest replacement bulb

Hmm, if you have to keep it in micro form factor there aren't many choices. These are the ones I know of from theatrical companies:

320 lmETC S4 Mini - Tungsten
376-607 lmETC S4 Mini - LED (depending on lense/LED options)
700-988 lmETC Iridian FPZ (25-50 zoom)
948-1151 lmChauvet Pro Ovation ETD-40WW (19-36, track mount)
*Altman ME4 Plus (30-40,

I'm not familiar with any of the more architectural oriented fixtures, maybe @Kelite or someone else from Apollo has some more suggestions? It may come down to choosing either to have it be discrete or bright, it is a pretty huge ask to get S4 intensity out of small optics and heat-dissipation packages.

*I really wish there was more consistency in what metrics were listed in specs 😡 (though it is getting better with TM-30 reports becoming more common).

Based on your photo, it doesn't look as bad as I thought. Seems like if it was "open" color and doubled the lumens, you'd be ok.
I think @josh88 answering my question about Ikea also gives you a better "small" fixture choice

My other though is: a source four and a beam bender. Then the light isn't hanging straight down and may be able to be hidden more easily.

Thanks! That chart is helpful. I agree about the consistency in metrics. Some use candle power, some use lumens, some lumen specs just seem way off the chart.

I like the beam bender idea...that just might be the answer. Then I can mount it to my 750s and etch the arrow into the ground with the raw power ;)

Actually, I might get one and test on my S4 JR...

Have you considered using Neutral Density gel on the sun to take it down in intensity? That should give you a better contrast to the S4 Mini.
In the mid seventies, our local TV station produced a year round noon hour show from one of four levels of our lobby. One of their two larger mobiles would park in a drop-off lane and they'd run in triax for up to five cameras; a normal 3 camera set up for the host, guest, and cover shot plus one or two more cameras for acts such as jugglers and animal acts further across the width of our lobby.

The lobby windows were floor to ceiling (~15 to 18'). Over the course of each year, the angle and intensity of the sun would change, along with the bounce from ice and snow. The station supplied wide rolls of neutral density of two saturations. One of our regular IA projects was installing, removing and rolling the ND gel with minimal damage.
Toodleoo!

I used to HATE gelling windows with #85 or #85+some ND. It often would have been easier to light with white flame carbons & use an 85 filter on the camera.
