    This is an alert for those of you like me with an exposed refugium light that is not enclosed in glass and that may be as close to the water as safely possible. A couple nights ago I saw something rather disturbing - my refugium light was flickering. Upon closer inspection, my eyes really opened when I discovered my bulb cap was very corroded with rust. I was just cleaning the lens prior and thought that was enough. Apparently not.

    An expensive LED bulb, trashed. I quickly scrambled and set up another fixture with a curly bulb from the hardware store. And this time, I wrapped electrical tape around the bulb and socket.

    Perhaps a compound like dolphonite would be best, but this should do for now. I will be inspecting this more often. What would you use? Is there a solvent that could repair my old bulb and socket? I want to hear from you.

    And check your refugium light for corrosion! :shocked:

    Clean it with CLR Calcium Lime Rust remover. I had my MH that would get like that and that will clean it up. Then you can put bulb grease from the auto parts store to prevent future corrosion.

    No problem sir! I thought I should raise the flag on this.

    You rock Rolo! I was hoping there was something like that. I will get both of those soon. Cheers! :beer:

    Truth be told I will save that LED for something else. It was not the best for growing chaeto. Those 6500k 23w curly daylight bulbs work best for me.

    Your welcome. As far as a light I did have the twisty one that worked really well for me. Then I acquired an LED from MarineLand that worked really well for me.

    It's CFL bulbs for me. I'm having too much success to switch.

    I PAR metered them.
    Each light was putting out 400 PAR about 1-2" under the water surface.

    Good find on the corrosion Matt.

    As a side note, now that I sail almost all fresh water on my Catamaran here in WI, my boat has zero corrosion, and I never have to fresh water rinse it after a day of sailing.
    That SW will corrode anything. It will corrode the corrosion!

    Yeah I love those bulbs. And I hear you about the SW boat issues. Mine has been sitting for some time until recently and awful things happened. Best way to kill a boat is to let it sit there. I need some hobbies that don't require maintenance! :lol:
