DIY LED U-Home 5M SMD5050 LED Strip Light Ice Blue Color Non-waterproof for Decoration Room Shopping Mall Kitchen Office Seasonal Celebration Lighting (Non-waterproof)

The LEDs were used in a special effect during a video production of "Mystic Office". I started by powering the string from 4 x 3.7V Lithium Ion batteries in series. The LEDs were way too bright for the scene. I ended up using only 2 x batteries with 2 x dummy cells. Very good product

This strip is advertised as 470nm - 490nm Cyan however is using ice blue LED's instead.I bought this because I wanted a bluish-green LED strip with more color saturation than RGB strips offer. Cyan is a rich blue-green color, as shown in the first photo -- the laser dot to the right of the strip (488nm). The ice blue LEDs are nowhere close in color to what I was looking for - they are closer to white than they are blue. Pretty disappointed.

The LEDs showed up in 2 weeks and are perfect! I needed Cyan LEDs a very specific project and they are great. Will most likely be buying more.

Wow, real cyan! Very pleased
