This light has the build quality that I've come to expect from the WF-504B. I had already ordered several with either XRE-R2 and XPG-R5, this is the first XML-T6.
Sturdy, nice finish, even lubricated O-rings.
Very much impressed with the amount of light!
This light appears to be direct-driven.
When you have a battery that sags in voltage only a little, you may overdrive even the XML LED.
With an older grey Trustfire battery, tail cap current is 2,5A, which is OK for the XM-L.
If you know this, it is not much of a problem.
It is wise to wrap the drop-in with extra copper or aluminum tape, so thermal contact between drop-in and body is improved. With an LED outputting so much power, you need all the cooling you can get!
Unbeatable for the price!
