I've got these Chinese generic 10w LEDs (pic related) and they're pretty good, except they seem incapable of doing 10w.

At 9.3v it's pulling 0.18A, at 12v it's pulling 0.7A, but at 12V it gets so hot it burns itself unless attached to a heatsink.

If I run it at between 9-10v, do I still need a current limiter?
It seems fine, it doesn't even get warm after a couple of minutes.

They are rated for 9-12V but the listing advises a resistor if used at 12v...

Apologies if this is a stupid question.
