How To Measure Fluorescent Tubes

Many of us don’t pay attention to our light bulbs until they burn out and when they do, it can be difficult to know exactly which size, shape or style you need to replace the bulb in your fitting exactly.

If your fluorescent tubes have recently fizzled out – don’t panic.
