2d 4pin LEDs: ballast?

    Hi,

    I recently purchased 2 of these LED 2ds to replace the flickering CFL 2d's in our hot press: https://www.ie.screwfix.com/luceco-led-2d-bulb-2-pin-750lm-6-5w.html

    While the website and the box for LED 2ds says they should work with existing magnetic ballast, the LEDs are flickering also. So I think either they're not compatible with the existing ballast or the existing ballast is out of action. Its at least 7 years old.

    Any thoughts on whether these would work safely with the ballast (correctly) bypassed? I removed the starter, and left the rest of the ballast in place...and they seem to work OK, but don't want to leave it like that if it causes problems.

    I've contacted Luceco but no response yet.

    If it means replacing the ballast, I'd nearly just remove the entire fittings and replace with a short pendant/B22 fitting.

    Any thoughts welcome.

    they're a 2-pin bulb so the fitting just needs the ballast in series with the bulb, no starter

    you need the magnetic ballast and starter or just the electronic starter for the 4-pin

    That's what I was thinking. They flicker when I had the old starters (as was the case with the previous cfls) so I think I need to try replacing the starters. I take it the same as those in this photo will do? Says "4-65w".

    it's me back, the 4-65w starter is fine


    it's good practice always to replace bulb+starter, the magnetic ballasts don't give much trouble

    what i have seen is new 2D bulbs give trouble like that

    best to switch to led rather than replacing parts
