Issy currently uses the old style bulbs, some of which are halogen, others are fluorescent.

Put together, these consume a total of 128W -whilst that doesn’t sound like a lot, it works out to 10.6 amps. That’s less than 4 hours running time on our battery!

An upgrade to LED bulbs means that in total they consume just 14.16W, or 1.18 amps, so the bulbs could run for over 36 hours – or about 9 days usage.

The bulbs are just as bright, if not brighter than the original bulbs, total cost was about £10.
