Hello
has anyone actually tested the beta QR 219a HCRI on a sphere, and checked what the actual HCRI was?.
Prometheus lights state it's around 90.7 according to the picture in the link here;
http://www.darksucks.com/store_BetaQR.html
They also state typical CRI is 93 in their LED's.
maybe that is correct or just marketing the HCRI - because I read that the higher the amp, the higher the CRI is.
ok, so these qr's run on AAA, so this is a low amperage.
I wondered how would this reach impressive 90.7, when some other lights driven at 1 amp+ reaches 85 to 88 cri and are in the neutral category, And near 2amp+ then you can get very good around over 90 then its HCRI.
is this correct?.
would these be neutral rather than HCRI then really?.
is the 93 just a guide?.
could someone test their QR on a sphere and see?.
Confusing, because to me these lights look the part of HCRI!. Everything pops vibrant colours!.
I hope that makes sense because my head hurts!,...and as always, Jason Hui's lights are still the best!!!!.
thanks.
