This two kinds of light are the one I wanted to put into my projects, I think the cost of those two lights are cheap. In addition, they are easily to install.

Here at Flexfire LEDs we use both 5050 SMD LED strip lights and 3528 SMD LED strip lights. Our LED strip lights come in Warm White, Bright White, Red, Blue, Green, RGB Color changing, and more!

RGB Colour LED

This article documents some experiments with achieving accurate, characterized, color reproduction from Lamina Atlas RGB LED lamps.

During and since construction of my driving circuitry for RGB LEDs, I have wanted to characterize the color output, both (1) for my own edification, and (2) to facilitate calibration of the color output to a defined color space, such as the sRGB of a typical computer monitor.

I recently leased an X-rite Colormunki spectrophotometer suitable for this task. The following describes the data I was able to gather, and how I've used it to calibrate for accurate color reproduction from the lamps.
