This ballast says it's for 400w MH and HPS lamps. It says no ignitor required but also says 'only for philips and osram lamps'. I am confused about if it would run these lamps.

Red..? What MH lamp did you get that claims to be red..? That colour is virtually impossible to achieve, see here.

I have coloured lamps from BLV, they seem the best in my experience, also Iwasaki (Eye) of course.

Was in 2012, at Rio de Janeiro, when they retrofitted the Rodrigo de Freitas lake pedestrian lighting with the GE envolve Iberia fixtures
Today they are no longer there and had been replaced by new bad quality LED street lights

I wanted to find orange :a_son-t: , daylight :a_mh:  and green  :a_mh:  HIDs in the same wattage.
Today, on my hunt for a 150w green MH, I found a 400w blue MH and 400w red MH along with 400w gear.
I will still try to find the trio. Either 150w orange HPS (have), white MH (have) and green MH (not double sided) or 400w orange HPS, white MH and green MH (have).

The ignitor you can check using an (old) AM radio.
When the ballast with ignitor is powered without a lamp, the ignitor makes a lot of RF mess that could be picked up by the radio (mainly at the bottom end of the AM band). Prezence of a buzz signalizes the ignitor is trying to do something, but it still could have some HV insulation problem.

After you manage to pick up the resulting buzz, try to connect a piece of wire (0.5..1m spread across the desk; be careful to have its lose end well insulated) to the lamp live terminal. If the buzz becomes way stronger in the radio, it means the ignitor is generating the high voltage, so very likely is OK.

I also wouln't be surprized the lamp did not survive the transport after being used for some time (spot welds connecting the arctube tend to weaken over time and then crack way easier when the lamp is moved around). To test it you may also use one of the ijstant stsrt fluorescent ballasts. Normally these are able to ignite quite fatty discharge in HPS, so good to test the lamp integrity. Of course, you should not run it for longer than a few second, such low power is not able to warm up the electrodes so the HPSwill suffer on it, but for a brief check of the lamp it is good.

Funny you mention this tunnel, Tim!  ;D I traversed through this very sad-looking SOX installation just last June.

My parents go through this area year and have for many years now, so I'll ask them.  :bulbman:

 @ Burrito : The Mission Bells are made by GE entirely from GE M-250 & M-400 parts . There's two on eBay : https://www.ebay.com/itm/353203073331 (M-250 parts , 100w HPS) and this : https://www.ebay.com/itm/165525545458 (M-400 parts , unknown wattage/lightsource)

 I don't know the status but I read that's there's been discussion of renovating the tunnel for a few years now.  I wish I could find photos of the original MV lighting ! It was nothing like I've ever seen before !
