Fluorescent Tube Question.

Q.1. With an old conventional 5ft. fluorescent tube that is controlled by a fluorescent starter unit and choke, what happens if I reverse the tube in the fitting and switch on?

Q.2. What happens if I convert the old fluorescent fitting to accept a new HiSpec Thames 25 W 110-240 Volt L.E.D. single ended tube and I reverse it in the fitting and switch on?

It's probably slightly safer than the earlier design that could accept L&N from either end - the pins at one end were directly connected to the pins at the other end - so if it was inserted one end first into a live fitting the exposed pins on the other end of the tube would be live.

There is little or no chance of touching live pins in this instance, even if the end pins were connected in parallel. The tube will be inserted into both lamp cap slots, then rotated by 90 degrees. This action will then liven them up. So there are no exposed live parts. Even with the old spring tensioned lamp caps I have rarely found the need to touch the tube pins when inserting a new tube.
