Nope. There are so many reasons why it would be impractical, including run-up time and the intense pressures required.
But it would look crazy cool, with pixels fading out, starting up with flickery flashes and runnning up through mercury color as you used the computer.

That's what I thought as well. The E denoting enclosed lamps was in the lamp part number and not the ballast code.

Really? I would have thought that would be in the part number (like LU100E or something as opposed to the ANSI code). Also aren't pretty much all HPS lamps rated for exposed use?

You may have picked up some parasitic (harmless) current under favorable weather conditions and high field strenght (multiple kV/m) to make this current perceptable. It went through your body (head, torso, arms) upon touching the metallic brake handles via the bike frame and tires towards earth.

Next time, take a 5ft fluorescent tube and stick it up under the power lines at night. There's a good chance it will faintly light up.

 @rjluna2 - There's always something for everybody on the internet. 

 @suzukir122 - I 100% agree. Lights are more than just a bulb on a pole, they reveal a tremendous amount of information and insight about the history, design, technological standards and legal codes of the area you find them.

 I've had few problems with the EcoSmart bulbs . I have several running D2D for over 5 years .

 Means the lamp is for enclosed fixtures only .

Almost all americal HID ballasts have ANSI ballast codes on them, whether it be M59 for 400W MH, H38 for 100W MV, or S55 for 150W HPS among others of course. But on the etch of many lamps (especially MH and HPS) I see a lot of them with an "E" suffix, like M59E or S51E or whatever. What's it mean?

Three people in a shift is absolutely crazy! That is an incredible
