Hi,

I have one of these…

Philips T8 Triphosphor Fluorescent Tube 4ft 36W-Colour Warm White (3000k), G13, 36 W https://amzn.eu/d/aG48ePY

Not working tonight and just flickering. Went and got a new starter from Toolstation and it’s still the same. Doesn’t look burnt out, but when it’s trying to turn on there’s two dark patches either side but not sure if they’re normally there but it’s usually too bright to see them.

Do I have to replace it with these bulb or is there a modern equivalent?

Can I use something like this? Also, the original bulb is 36w but is that a different rating with an LED bulb? It’s 18w but what does that work out if it was an old style bulb?

Thanks
