Output graph for Wolf Eyes D2AX with cree

[cchurchi]

I was planning on getting the Huntlight with the cree and running 1 X 18650 but the output graph shows the output droping right away rather then being regulated and having a flat output. I haven't seen an output graph for the Wolf Eyes D2AX with the cree head (offered here)

Anyone done any runtime and output tests with a lightbox on this light with an 18650 rechargeable Lithium ion battery?
