Just wondering if anyone has any idea what type of lamp that I noticed lit up in the so-called yardblaster.
It's a coated lamp with a very bright white light but it seems like it has just the very slightest hint of a pinkish hue.
I have no idea how old it is.
Couldn't get a picture because of a combination of my phone camera and because it's on someone else's property.
Any ideas??

I’d guess it’s probably a coated MH? If not it could be a very new /DX MV.

Is it really an HID?

If it is something really new, it could be one of the Philips "TForce HPL-LED" retrofit lamp...

As far as I know that lamp is likely from the 90s, but it doesn't get used very much.

What you describe of sounds exactly like a coated MV lamp.  It being from the nineties also kind of confirms that.

I believe that in the 1990’s, there were no yard blaster type of fixtures that ran metal halide lamps. That would make it very likely to be a mercury vapour lamp. Have you been able to see it strike and warm up ?
