Wow That would fit into my 400 Watt Mercury Vapor Lamp and Makeshift Fixture nicely.

Pretty, please no more Chinese failure.

Nice lamps! I have several of the ~1980s GTE version. Interesting to see tubular MV lamps. They work nice in fixtures intended for HPS lamps where an ED lamp may not fit.

I agree, since the mid 1980's these types of Mercury Lamps became discontinued, as users decided to use Elliptical Fluorescent Mercury Lamps, and Tubular Metal Halide Lamps, by simply adding a Ignitor, in some cases where colour wasn't important they replaced the Tubular Mercury Lamps with Tubular High Pressure Sodium Lamps, example a 220w SON-T lamp on 250w Mercury Gear and 310/360w SON-T lamps on 400w Mercury Gear.

Sylvania pretests their lamps...that's why there is blackening at the ends.

Do not argue with an idiot.  They will drag you down to their level and beat you with experience.

Yep as WestinghouseCeramalux mentions this is Manufacturers Pre-test which has caused the slight blackening around the electrode (Cap End) normally if the lamp has been lit for 20 or so minutes this disappears.
