Fluorescent Lighting in Sheds Help Please

That light is small money, Ansell are a good brand, i have several Ansell floodlights that i can't fault.

The one you linked is 5ft, the one you are replacing is 4 ft so you'll definately have plenty of cable for the new lights.

I put up 6 of them screwfix light during the week, but the twin version. The ones you have attached are a single version. It's the equivalent of a single tube vs a twin tube. Worth the small bit more to go for twin to throw more light. Fine fitting with good light and would have no issues using them. Replaced tube fittings that went up in 1997

Small tip with these is make sure to drill the cable knockout for the gland with a hole saw as it doesn't knock out clean on these

You could just convert the fluorescent tubes to LED. Take out all the ballast/starters etc and wire them up direct. It's the simplest way and does away with the need to take down one fitting and put another back up.

Fitted 4 of those lights to replace the single 100W bulb my dad used to light his shed.

Super simple job.

I think your existing fittings are 5 foot. I know it comes up as a 4 foot in the link but the photo you show of the existing one is a 2 x 58w fitting which is a 5 foot. Measure twice, cut once.

If you can see inside the back of the original fitting check where the terminals are, if they are off to one end and your new fittings are in the centre you may have problems wiring.

I learned these things the hard way unfortunately.

If putting up new units, either 4 foot or 5, then an extension ladder isn't good enough.

You are going to be holding a light unit in one hand, and probably a battery drill in the other while trying to co-ordinate the two to run in a Tek screw.

Unless you have 3 arms this leaves you balancing up a ladder 18 feet above the ground/feet passage .

Hire, buy or borrow a few lifts of quick stage scaffolding, or get someone with a Teleporter and a proper man cage.

I see this one in the local hardware Christmas booklet, looks like it's light duty enough but it's an idea of the price of them, working height of between 2 and 4m saucey enough even at the discounted price
