What can you tell me about the heat output of these? I don't see much in the way of heatsinks or ventilation there.

I'd love to be able to retrofit two of these into a 48 inch striplight housing as shown, but there's far less venting on those than what I have.

How does the heat output compare to your 2x36, both above and below the light?
Hi tsonnenl,

I didn't compare the temperature of the 24" LED lamp array fixture to the 2X36 watt PC but I did compare it to an AHS 1X55 watt (24") fixture.

AHS 1X55 watt PC = 92 degrees F.
AHS 1X20 LED lamp = 84 degrees F.
Ambient temp was 76 degrees F.
(Measured by putting temp. probe between fixture and glass Versa-top.

Hope this helps!
