This is from the manual which I am not sure that I have ever seen before?

So it seems to replace the Turbo with High on an Eneloop and does seem to have just 2 speeds unless you know otherwise.

“After switching on the flashlight, long press and
hold the button for more than 1 second; the
flashlight enters ”Low - Medium - High ” modes in a
cycle. Release the button to select the current
brightness mode. Ni-MH / alkaline batteries for
LOW and MID mode cycle.
Turbo Mode
When the flashlight is either switched on or off,
rapidly double-press the button, the flashlight
enters Turbo mode. When using Ni-MH / alkaline
batteries, double-click the switch button, the
flashlight into the HIGH mode.
Moonlight Mode
When the flashlight is switched off, long press the
button for 1 second, the flashlight enters Moonlight
mode.”
