Default 396XT current draw with various LED colors & brightness

Measured the current draw at different bightness and LED colors on the 396XT. Here's my findings

With lamp off and battery saver turned off while sitting on one conventional channel the current draw with no LEDs on is 157mA while no signal is being received

On the same conventional VHF channel, now we turn on the LED and measure the current:

High Med Low
Blue 197mA 180mA 172mA

Red 195mA 182mA 171mA

Mag. 220mA 196mA 177mA

Green 200mA 180mA 170mA

Cyan 220mA 195mA 176mA

Yelw 220mA 197mA 177mA

Whte 250mA 208mA 183mA

On bright LED setting, there's more than a 50mA difference from red vs. white.

What surprised me was red draws as much current as blue.

White uses all colors (RGB) to produce white, so all 3 leds are being lit at one time.

The primary colors Red Green Blue draw the least current, as they are just lighting 1 LED. Any other color than RGB, 2 or 3 LEDS are being lit to produce that color, hence drawing more current.

Great work you've done, as uniden doesn't state the draw. Any figures with battery saver on , and not scanning, and while scanning.
