How many lumens are these? Please do not answer “I don’t know” as that is useless; only answer if you know the answer!

Since the KL400 doesn’t utilize white LEDs, there is no technically no measured value of lumens.

However, since the KL400 can simulate white light using color combinations via its RGB LED technology, the brightness of this value is equivalent to 400 lumens.

why don’t you show the power supply in the pictures?

Power supplies are ugly, maybe? It’s a standard “wall wart” type of supply. It’s black.

I want to stick it behind my tv, can i cut it to make corners and reattach them with the l connectors?

To make a 90 degree corner without cutting or soldering:
1. Say you are starting on the left side of the TV (from the back of the TV) going vertically up the back of the TV and want to make a 90 degree turn to the right.
2. At the turning point, make a 45 degree bend to where the LED side is facing away from you and the unattached portion of the strip is now pointing to the left.
3. Then do a 90 degree bend so it comes back over the 45 bend and is now going to the right as desired and the LED side will be facing the same side.
(Reach out if that isn’t entirely clear.)
