Drive current for UV LED

I’m going to put together a UV P60 using this Noctigon/emitter combo.

I plan on using a single mode, Nanjg 105C pulling off 7135s to achieve the desired drive current.

The question is what should I drive the emitter at? Intl-Outdoor states “Vf tested at Max. 700mA: 3.7V. Does anyone know if 700mA is really the max drive current? Is there anything to be gained by running it at, say 1050mA?

Thanks for any responses.

I ordered one and will try to generate a useful current/voltage/output curve when it is in.
