    Should I change the tube? Where can I get this tube or any one has new tube for sale?

    Thanks
    It is really up to you and how your plants is responding.

    Personally, if the plants is still doing fine, I will leave it until it burns out. Usually, the lights we have is in excess of what the plants really need.

    Poorer quality lamp do exhibit shift in colour and brightness significantly as it ages. So far for me, better lamps, seems to retain brightness and colour better.

    I'd noticed most if not all 55W PL lights (the 4-pin type) do not have proper light holder for it. Most shops (including NA), improvise by using a row of H-type connectors. This does not allow quick-release and it requires a test-pen screwdriver to do the job which can be quite dangerous for an untrained hobbyist. Does anyone knows where to find such light holder? I did not call Lian Eng Electric cos' I find it difficult explaining to them in Chinese.

    julescity,

    Your thread was moved to a new thread.

    Every lamp without starter incorporated, needs electronic ballast to function and also with appropriate equipment can become dimmable!

    if i have a 1ft tank with downoi, and want to use a PL light, approx which wattage should i need to use?
    my tank should be about 10 gallons right?
    so if what 1 bro here says 3wpg, then it should only be 30 watts.
    will this be sufficient for downoi or ericaulon?
    thnks

    Overtime the bulb lost its spectrum and causes algae growth. But in my tank I usually change it like a year and 6 mos.

    Re: Types of PL lights

    Hi,

    There is another new PL lamp which is not mention in this thread.
    It is a electronic PL lamps to replace the old 2pin PL lamp+starter type.
    This PL lamp uses about 30-40% less energy to light up a PL tube.
    The current used is only about 1/4 of normal PL tube with a magnetic ballast.
    This also means that it generate less heat.
    The lamp do not have starter, this means that the tube can last longer without going through much flickering when the lights turned on.
    The PL lamp can also be connected directly to 230Vac instead of going through the ballast.
    It is available from saveOne. They have a power meter for customer to compare the advantage of this new PL lamp.
    For those who are concern about electricity bill, I think it is worth changing your lamp to energy saving type.

    Re: Types of PL lights

    Hi spider,

    saveOne is in Havelock Road and near Bukit Batok area
    You can check up the website for the actual address and direction.
    www.saveone.com.sg

    It is a new product.
    I have done a comparison table between saveOne lamps and other lamps today.
    You might be interested to take a look at the differences.
