Hi SunnySkyguy,
thanks for your comments.
For the LED drives I used IRL3705N which can handle up to 89 Amps of current per G,R and B channels(at least theoretically). This means that you can drive a lot of LEDs on the strip and by that lowering the total cost.
You can linearly change the light by sliding the finger on the remote colour wheel. By just taping on the remote you get fast colour transition as seen on the video. The lamp LEDs are driven by PWM so you can unfortunately see the flickering. The PWM is running at few Khz so it is not very noticeable.
