On the 1theDeals listing page for this it says “High Efficiency Direct Drive Driver”. I’m not quite sure what they mean by that exactly, but I hope it means what it sounds like it means. Some form of decent sustained output.
Edit: It sounds like their talking about the turbo cause they say direct drive, but I’m hoping it’s their way of saying decent sustained output.
Tried to search for “SFQ43” and this result came up:
There is a photo of a triple-LED flashlight with allegedly “SFQ43” LEDs, and they look like ‘domeless’ LEDs (ie. similar to the Cree “Hi” series or similar also to the SFS80, SFN55.2, SFH LEDs which are also domeless LEDs. SFQ43 seems to be composed of 4 smaller LEDs (the SFN55.2 appears like a combination of 3x3 = 9 smaller LEDs, while the SFH appears like 4x4 = 16 smaller LEDs. Maybe the SFQ43 is 2x2 = 4 smaller LEDs, just my guess.)
