Nichia 219's listed as "white" 5000K? Worth looking at for a "less yellow" beam?

Texaspyro, how do you test the temp range?

Any interest in a LED/Battery analyzer device?

I am building a device for analyzing batteries, LEDs, drivers, flashlights. As planned it would have: 2 × 30 amp hall effect current sensors (< 2 milliohm burden resistance) 2 x type K thermocouples (good to 1000 degrees C!) Battery and LED voltage monitoring (up to say 50 volts) LVC cutoff FET for the battery Light sensor input (digital and analog sensors supported, 50K-100K lux, integrating sphere supported) RS232 link to computer / monitoring, graphi…

I also have a couple of formulas that calculate the CCT directly from the CIE color coordinates generated from the color sensor readings. They don’t seem to be as accurate at the moment…
