Received brand new PH50 to UK! Looking good. Both batteries charged now.
I had a look at the bulb before I switched ON. Yes mine has the same yellow "bits" inside. What made me more unsure was the fact the yellow is only on one side of the bulb as if it came to rest there once cold. Maybe from manufacturer testing?
I turned the unit ON, heard the whine and WOW that is really bright. So bright my head hurts actually.
First thing I noticed when shining it on a wall...
Half the corona nice and white, the other half...yellow tinge! That's definitely down to those yellow "bits" and more so on one half as I'd seen on the bulb glass before powering it up.
Makes me wonder whether the bulbs are defective or not, but, I did a few google searches and this is what I've found... FAQ Polarion.
Q. Why does my beam pattern appear to have "artifacts", a yellow color in the corona and black line it when I shine it at wall at close range?
A. The Polarion HID searchlights are factory pre-focused for extended ranges of 150-200 yards and beyond. The beam pattern will not look perfect when shined at a wall at close range. The yellow in the corona (the less brilliant area around the center "hot spot" is a result of the sodium in the lamp itself and is perfectly normal. This pattern will change depending on how you orient the light as gravity moves the gases around. The black line is the shadow of wire that runs parallel to the glass tube of the lamp.

After seeing beam shots on CPF and on YouTube, I'm not overly confident that this is normal. But yes I was shining on a wall within 10ft of me. Actually, my eyes really do hurt!
It's just started to get dark here in the UK so will go out later to see what it's like.
Polarion guys, any comments please? Thanks.
