I was wondering what the max surface temperature for the KL130 is.

Trying to run it in a semi-enclosed fixture.  Surface temp reaches 74.4⁰C with 23.3⁰ ambient.  I know there's components that can survive that temp but the question is if TPLink chose them.

I really don't want to put a 40mm fan in them.

Edit: FAQ on the website says enclosed fixtures are ok because "They generate no heat" which is bs, the box and bulb day do no use in enclosed fixtures.
