Bad Grunff, very dangerous advice.


Weeeel, I did describe the correct way round, be fair.

But in ES fittings where the thread is plastic (like this one), and
contact with the bulb's threaded part is made at the bottom of the
fitting via a side spring, it's actually very difficult (impossible on
many fittings) to touch the bulb's threaded part while it's in contact
with the terminal - so it doesn't make a great deal of difference.

I personally think ES are evil and should be banned anyway.
