• don't flicker like fluorescents do

    From August Abolins@2:221/1.58 to Kurt Weiske on Wed Dec 14 18:28:00 2022
    I replaced some fluorescent bulbs recently and found LED tubes - they're the same form factor, but inside are a line of LEDs. They lightg up quickly and don't flicker like fluorescents do.


    When I took over the shop, the previous installation had a
    series of 8ft-long and 4ft-long fluorescent T12's. When some of
    the transformers started to fail after 2 or years of my
    occupation, I had all the T12's changed to support T8's. That
    was 7 years ago. Now, some of those "new" instant-start
    transformers are failing. I am at the point where direct-wire
    LED tubes would be a more welcoming solution. But the 8ft-ers
    cost about $32 a piece. I would need about 24.

    I am not sure if I've seen any other retail space using LED
    lighting exclusively.

    I've gone through at least a handful of T12 fluorescents, in my
    first couple of years of operation, and then even MORE T8's
    later on. At about $20 a piece, they could add up.

    But the LED variety cost even more.

    Which kind did you settle with? Direct-wire types, or the ones
    that work with the existing ballast?

    I bought mine (60 cm T8) from AliExpress for about 5 EUR each (free shipping). They were connected so that all I had to do was remove the starter. Removing the ballast is optional.

    I thought ballast=starter. So, it looks like you got "direct-
    wire" types. That's the way to go.

    I'm surprised that those tubes have "holes" for cooling. I
    didn't think they would heat up at all.

    Mine need to be brighter. I have a 12-14 ft high ceiling.
    And I need 4ft and 8ft types.
