Ok, so I have finally found the time to add the new lights. These are 10w, 660nm 12 volt lights, for safety. A drip loop is in place and the power supply is located well away from any water and outside the cabinet. The power supply is also plugged into a 30ma RCD, standard for domestic use in the UK. It is not an ideal situation, but hopefully it will work for a while whilst I continue my research.

The rubbish led strips provided with the unit were almost falling off and not very efficient. Even with the increase in lighting time, only 19g was being produced on a fortnightly basis.






Because the slot was so small, it blocked easily causing water to squirt around the enclosed spray bar area. As you can see, almost as much algae growth on the window as there is on the screen!




I bought myself some waterproof connectors and connected my new lights up and tested them. Mounting the lights on the scrubber was not an option as the light would be too low. Some bargain window board was cut to the width of the scrubber, fitted in the slots and lights attached Just for safety's sake, I taped the board on the outside as well, "just in case". A tip I saw on another forum was to cut some filter tubing an cover the 12v connector fittings and (hopefully), prevent corrosion, although these are also outside of the cabinet now.












And there it is, running with the new lights. Hopefully it will be better than what was there previously and I will now get some good growth. I am thinking I may need 2 more, so there are 2 on each side and giving full screen cover.
