Hello,
First I would like to apologise if this is a very basic question, I know next to nothing about electronics and power supply and such.
I'm trying to build a moth trap and would eventually like to use it in some remote areas and so I won't have access to the mains, and generators are rather expensive so I bought a battery.
I currently have the battery and the bulb and want to know if I need an inverter to use it, and what kind.
The battery is an Eco-Worthy 12v 20ah LiFePO4 off ManoMano, and the bulb is a 240v 20w Sylvania MLX E27 blacklight. The inverter I found was a Streetwize 12v - 240v 150w inverter.
I found one inverter and in the process of looking up what connection it came with, I found it was not suitable for fluorescent bulbs. However, I've found information that I may instead need a 240v - 12v inverter, which seems counterintuitive as the lamp runs off 240v?
So all in all, I am confused.

Thank you for reading, and I hope you can help.
-Josh

There are small inverters commonly used to power fluorescent tube lights - many of the older type 'emergency exit' lights have them fitted - that could serve the purpose. You do, of course, need one designed for a 20W lamp. Here's one (not a particularly good example due to the use of a wirewound resistor as the transformer!)

and here's one using the 'right' transformer:

There are quite a few DIY projects outlining the build of one yourself if you're that way inclined. If you are UK-based I think I have a couple of suitable units I salvaged from an overhead projection unit you could have.

Thank you for the information! I had a look at those DIY ones, but of course at the time I didn't know if they'd be the right ones.
I am indeed in the UK, and would be truly grateful if you could help out.
