For me, it depends on my parents and the cost of shipping. If both of those are in my favor, I would like one NEMA head.

For me it'll depend ultimately on how much it'll end up costing to ship it to Canada, so maybe a NEMA head as cobraheads are typically too cost prohibitive to ship to Canada.

So Lumex120 posted these lights. I think I live closet to the seller and wanted to pick these up. To make the trip worth it (i don't need 30 nema heads) and try to break even buying these would you buy a nema head complete for around $10-15+shipping? Want to know this info so i don't just have a few dozen mercury nema heads as i intend to only keep 2-3 and maybe some other lights. Your opinion is greatly appreciated!

Thanks ! I was curious since when I first joined a was corrected by a few members CONSTANTLY about "ED" instead of "E" . 

The lamp was made in 3/98 . Ge lists this lamp as "special application & black light. I'd guess it was used in some sort of lab equipment.  I have the Sylvania version which is made in 1995.

Not sure why they did that. Maybe it's because they realized they were using the wrong names for the shape of the lamps and wanted to put the correct names for the shapes?

My reasoning for the question was that in my older lamp catalogs I can find a lamp listed as "E-28" but in a new catalog , the exact same lamp is listed as "ED-28" even though both are absolutely identical in shape and form . WHY ??

No !  They declined my offer this time . I'll wait a bit and see if they get desperate and try again .

Anyone know what the 2 floods are in the 2nd pic ?

Interesting !!
