Your original light is a "CFL", which is a fluorescent tube with a built-in internal ballast (that's what's inside the weird lump).
Since the old one is rated for 220-240V, clearly that socket has bog-standard household 240V on it (and not 12V or some weird ballasted current intended for a particular tube).
So yes, you are G2G to install any safe, legal light which will fit that socket. A safe, legal light will have
- a BSI stamp/certification, or TUV, CSA, UL or ETL mark.
- A CE mark but only if sold at retail at a respectable bricks-n-mortar shop
- Never something from eBay, Banggood or Amazon. There are 2 problems with Amazon: This
(shipment from an Amazon warehouse counts the same as direct shipment from China; this is a dodgy foreign seller). And this: products sold by Amazon proper can't be trusted because of Amazon Commingling. A counterfeiter dropships fakes to an Amazon warehouse and tells Amazon they're the same SKU as the genuine product. Amazon trusts them! And will commingle the fakes in the same bin. So even a trusted seller known to you, like Amazon proper, can ship counterfeits. Worse, Amazon may stop reordering genuine product since they're well stocked on that SKU, so the fake takes over the bin.
So, assuming there isn't some sort of pandemic running around, just head down to Wickes or a proper lighting supply or other reputable seller, or buy from them online if they do their own fulfillment in-house. And don't get snake-charmed by the low prices on the cheap Cheese.
