    With the increased usage of natural algal filtration, comes the increased usage of illumination to make the photosynthetic filtering process occur. However a certain type of metal-case light has come onto the market, and this light needs to be addressed because it is potentially unsafe when used on ATS algae turf scrubbers. We do not use these lights, but unfortunately other people do, and the corrosion of the metal case lets water reach the dangerous 240/120 volts inside. If you do not have these lights, then you can decide whether to get them or not. If you already have them, then you can learn how to protect yourself, although it safest to change the lights entirely.

    Over time, the problem of the metal case gets worse, not better. At some point the metal case will reach a critical point due to the corrosive operating environment of sump-mounted waterfall algae scrubbers, which is a much harsher environment than the outdoor gardens the lights were made for. Whether this is 6 months or 6 years depends on the light, the scrubber housing, the sump environment, and the usage. The simple solution is to just not use metal-case 240/120 volt lights. If you already have these lights, and you are not technically comfortable with electricity, the only safe solution is to have them replaced before corrosion breaks through the seal. Do not believe anyone who tells you their aluminum case lights will not corrode; all aluminum corrodes, especially near saltwater.

    Even if you have 1, 2 or 6 of these lights, and they've had no problems for years, that does not mean that other people should not be informed. Imagine if your car had a defect that only showed up for 1 in 100 people, and you were the one that got injured. Would you want the car company saying "There is no defect. We have a customer that has two of these cars and he's had them for three years; if there were a defect then he'd know about it." Of course not. You would want the pertinent information. And as a maker of LED lights, and being an Electrical Engineer, I feel I am qualified to provide this information. If you have additional information, you are invited to post it below, especially if you are a verifiable state-licensed electrician.

    Several "commercial" scrubber builders who use these lights were asked to provide input/articles to be included here, but nothing was received from any of them. Also I offered to provide free electrical design advice to improve the safety of their scrubbers, but all of them declined, saying their lights were not dangerous, even though they had no electrical training, experience, or certifications to back this up.

    The following is one person's professional opinion on the safety of metal case, high voltage, algae scrubber lights. You should consult your own professional advice and opinion from an independent electrical engineer, electronics engineer, electrician, or safety technician before using these lights; if you are making, advertising or distributing these lights then you should also consult with a product liability attorney specializing in electrical injury. Again, we refuse to use or promote these lights.
