"The use of cadmium is generally decreasing due to its toxicity (it is specifically listed in the European Restriction of Hazardous Substances[3]) and the replacement of nickel-cadmium batteries with nickel-metal hydride and lithium-ion batteries." https://en.wikipedia.org/wiki/Cadmium...

3.72umol/J from the blue source and after the phosphor conversion we have around 4.7umol/J....damned physics

................................................................................................................................................................................................wow... 3 voltage classes; 3 currents. that will give us a lot of threads and debating...(:

weighted, against what? "comes partly from the level response from 420-550" if you see a light source with a MCcree spectrum you would see a reddisch ligh, as this spectrum does not sit on or near the black body locus

1.there are different settings in the software xiv. “Limit umol/s-W to 400-700nm” Limits the calculation of the umol/s-W to the range of 400-700nm. If this is not checked then the umol/s-W will be calculated over the range of 360-830nm or 360-1050nm if the “Include IR” option is checked. can...

the Chlorophyll A/B response is included in the MCcree curve,.as this is the basic of photosynthesis. and the MCcree curve itself, sits well above 4000K with a CRI above 90 - near full spectrum warmWhite is like standing in the shade for a plant... depleted blue... but plants are smart and make...

80°C; a chisel, gentle force and some luck

thanks... as i thougt; different CCT* calculation based on CrPC-tools @ 25°C *

will check my math @alesh - would you please so nice and give me the Raw Data CXB3590 90CRI 3000K and 80CRI. just a bit wondering that the blue peak for 90CRI is higher then 80

both high CRI(90) versions have a minimum lost of about 10% lumenwise.

another tidbit... posted about 3 years ago... https://www.rollitup.org/t/cree-cxa-analysis.743645/page-2#post-9766199 seems you have some problems in understanding relative and absolute graphs

50% is very Inefficient....get some brain maybe it helps!

that´s spanish for you

from 400nm to 800nm we have one octave rise and fall happend in less then 50nm see McCree yeah

me too, but this drill press never come out in the blue line...

a tool for a fool like me

ledneck as Chinese people say
