-Yes, sure. Please provide us with drawings.

-Yes. The COB LED strips do fit inside the Aluminum mounting track for the 12V strip lights.

-To be completely waterproof, the LED strip would need to be in a waterproof housing-which could lead to overheating. The LED Seal product can be applied directly to the LED strip to make it water resistant.

–It is not required as the strip has 3M adhesive backing but in some applications, a little extra bond does not hurt.

-For example. The product is 14-Watts per meter. You would calculate the total length you need (in meters) and multiply by 14 to get your total wattage.
You should add 10-20% to your wattage calculation when sizing your power supply.

-The High-Power LED strips do require additional heatsinking, but the Flex strips do not require a heatsink.

The low-profile, adhesive backing and trimmable length makes LED flex strip easy to hide almost anywhere. Imagine a softly lit cove inside your living room, above and in decorative display cases, below cabinets, behind mirrors, underneath toe kick areas. Outside applications often include indirect lighting under hand-rails, porch railings, and eves. We have seen color strips on motorcycles, under vehicles and inside bars for a modern look and feel.

-A dry outdoor location would be okay. We would recommend applying a product like the LED Seal to the strip as well).
As for mounting, we do offer an aluminum mounting track that comes with a diffusing lens here

-Yes, dimming is available for both High-Power strips and Flex strips.

High-Power LED strips use LEDs capable of drive currents up to 700mA making them perfect applications that require more light than accent or indirect lighting. Our High-Power strips also have on-board drivers that deliver constant current and provide low-voltage dimming control. The Flex strips are much less bright, and obviously flexible where the High-Power strips are rigid. For example a High-Power LUXstrip can produce more than 1000-lumens per foot where a 3-foot piece of Flex strip produces 300-lumens.
