It is a simple thin and small tablet like led..Which LED units and make do you have might help a little
Yes, they look cool!I built a shelf and then hung my (very heavy) panels from that, using a hanging kit and some screw in hooks. It doesn't look great, but it works fairly well. If you have the budget the iQuatics hanging kits are lovely.
I would prefer not to drill ... But I will check those.Aqua Medic Aquafit has 3 different versions i use number 2 for my diy led setup.. But also TMC and ATI have these kind of cable sets in offer.
I wonder if steel fishing wires and sleeves are OK for this application?
