I test with the Eneloops right off the charger (within 20 minutes usually). I would think that the voltage drop when the light is turned on will be much larger than letting them rest for a couple of hours. That’s why I included the 60s number. The light temperature will have a bigger effect than the battery voltage, since the output drops very rapidly at the beginning but not at all after the temperature has settled even though voltage keeps dropping.
It seems your readings are very stable between different tests.
Meters react very differently to different wavelenghts as djozz’s latest lux meter test shows. For example, the noname LX-1330B reads 7.5% low on the 4500K 70 CRI Supwildfire Mitko thrower and 3% high on the 4000K 90+ CRI Sofirn SP33 compared to a good meter.
Awesome. Thank you. I’ll call these results good, based on this particular dr meter. I’ll just re-run calibration every once in a while to make sure the sphere is reading what I expect.
Nicest part is now that I have your calibrated test lights, I can grab a better meter, down the road, and recalibrate accordingly.
These test lights are really a game changer for the entire hobby. Thanks again for offering them.
Yes, I’m okay. Thanks for checking Maukka. We’re in alert mode and stay away from the river and shoreline. Sulawesi shares the same tectonic plate with Bali.
