Mounting kessil tuna blue in current light fixture

[Deej1534]

So I have a currently working t5 light fixture which used to have HiDs on it but they fried out. I have 3 kessil tuna blues I wanna add to the fixture to replace the HIDs and make a hybrid set up. Would adding them in the below pictures areas be okay or do you think they would over heat?

Keep them under 80% to minimize heat. They do have fans, so that helps

I am thinking how hot my HID’s were and these mounts kept them fairly cool. And the whole top of the figure is venting. When they are placed in the fixture there is about a 1/4 inch all around
