Oh thanks Professor! Mars did a giveaway on that light a few months back but I didn't win so I forgot the model number.It's Mars's new square light. I'm not sure how it's different from the SP's but it looks like it maybe has warmer light.
Not sure on the color temp of the SP-250 but I can tell you that when I get the most accurate pics with the color temp on my phone set at 4000K, if that helps. It's definitely cooler than the 3000K Samsung strips in the shed.
