The X6 SST-90 produces 1625 Lumens according to QCG site

The SST-50 Produces 730 Lumens.

The review on DX site state both have problems.

I think they are not good as XM-L for output per $.

XM-l Lights can produces up 1000 Lumen.

For throw the SST beat the XM-L but at a price in dollar terms, iwould go for XR-E light for throw.

IMHO, the price is a little expensive
