M400A during eclipse totality

M400A during eclipse totality

Click to view full size image

I took this picture when the sun was fully covered and only the corona was visible. To the east you can see that it is still not completely dark. This is a 250w MV M400A2 (yes, I know, odd wattage for a fixture this big) and the optics are kind of wonky with the small lamp in the big reflector. And the date is supposed to say 12:57 PM, not AM. This is in Friend, NE where there are also 250w PSMH AEL 125's. Only problem is they install them with the included lamps but then when the lamp goes EOL they stick a merc in it. Not sure if they disconnect the ignitor or not, but if the 12 (yes, I counted them) 125's mislamped with mercs experience a power interruption, that's going to be a pretty spectacular fireworks show.

The ignition assembly in the MV lamp will melt, explode, and flash very bright when used on a PSMH ignitor. I did this with some dead 175w mercs I had laying around, it is quite entertaining.

Any machine is a smoke machine if you operate it wrong enough.

How this can happen that during a total solar eclipse, the lower horizon is brighter than the higher sky?

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

That was east of where I was and so it wasn't fully covered in that direction. It soon became dark in that direction too.

I saw a 50% eclipse on the NH/MA line. Nothing spectacular. In 2024 we're supposed to see a near 100% eclipse here in New England.

BTW this is not an M-400A2. If it's a Powr/Door it's a M-400A. If it's a single door is an M-400.
