LED test / review - Luminus SFT-42R-WES (6500 K 70 CRI)

At lower operating currents (3 A, for example), however, the SFT-25R or an LED with an even smaller luminous area is preferable as long as luminance and thus throw are important.

Thanks for the excellent review. I was going to ask about SFT-42R vs SFT-25R performance, but now I just noticed you’ve pointed it out already . Noteably, even at higher current, like Convoy M21E with 8A buck driver, SFT-25R would out-throw SFT-42R , right? (And SFT-42R would have larger hotspot and brighter spill.)
