I had previously used small lights on a 2-wire cable. Here are more and more blown and Auswechslen was very problematic.
The LED strip with self-adhesive tape on the back can be excellent 'fit'.
The strips can be cut every 10 cm with the scissors and renew if necessary with cable. So you can in a display case at the inside of the door on the left and the right, for example, attach each one meter LED Strip and connect them in advance with a cable by soldering. Important attention to the polarity!
I leave the running with about 12 V DC, thus I need less power and the luminosity is slightly weaker. An additional dimmer is unnecessary and I can have a normal light switch off and on the transformer. It even runs on a 9V (battery) battery, but I have not tested the period until the final depletion of the battery.
A 3m Strip consumed in 12 V voltage a current of 420 mA, which is about 5 W. Thus requires a 3m strip in 200 h (= 8.3 days per 24 hours) a power of 1000 W (1 kWh). The consumption of 9V is 55 mA, about 0.5 W so only 10% of it. Mind you with a 3-meter strip with 90 LEDs! Course at 180 LEDs each double consumption figures apply.
Through the use of a transformer, the consumption increased depending on the type of about 10-30%, which is the economy in no way does an abortion.
The use in mobile homes, caravans and on the boat is possible because of the ideal voltage of 12 V without transformer and between devices.
