With regards to a constant “hot light”, the Solux 4700K is THE reference source to beat. Easily surpasses the SORAA LED in all regards. Take a look at the spectral distribution in the upper left panel, a D50 match. There aren’t any “hot blue” ramps like those found in the Profoto, Alien Bee or other flash units, nor are there any “blue pump” peaks like those found in 99% of the LEDs on the market. Glance over the right hand panels and you’ll find very little deviation from ideal. The bottom chart is a sampling of 99 different colors and their accuracy. Previous chart of the iphone 7 was quite ragged. Look at the Solux 4700K - darn near perfect. I’m using the MR16 4700K in my setup. Be advised however that the larger PAR38 Solux does NOT have the same performance and the CRI drops down to low 90s, R9 deep red goes down to mid 50s with the larger sources. Reason? In the large PAR38 / PAR series, only the bulb is coated with the patented vapor deposited film. The MR16 utilizes the ENTIRE interior reflector with the coating.
