A160 daisy chain

[Roy Arena]

I have three A160 daisy chained. The light which is wired to the Kessil controller is hot to touch. The other two are cool and fans are working on all three. Is this normal when they are wired in this fashion or is it something I should be concerned about?
Thank you

The fan or the cord is hot to the touch?

When I ran three 160's, I split them up between the two ports. Two on one and one on the other. Didn't encounter any problems, heat or otherwise. Try connecting just the one that's running hot by itself and see if it changes?

The housing was hot to the touch. I gave it some cleaning with a can of compressed air and now its seems the same as the other two lights. Thank you all for the replies.

Keeping them clean is a must. Five minutes once a month is all it takes.

If they are still running hot after cleaning them with canned air opening them up for a deep cleaning may be necessary. Double-check with customer service that is is out of warranty before you open it up - [email protected]
