[SML] pipe grid question

[Ford Sellers]

Devil's advocate...
You shouldn't need to replace 1 for 1 with LED, as many LED fixtures are color changing... So you'd only need half the fixtures.

I'd also submit that only some units weigh that close to twice as much.

How many and what is spacing of hangers?

And the half pipe clamps are the only thing holding it except perhaps flanges at the wall?  One for every 6' of pipe is around 30plf. (50 x
50 - say 13 pipes each way - 1300' - 200 units around 15 pounds average - 3000 pounds.  <4000 pounds of pipe.  How many hangers?)

I'm inclined to agree the half clamp is not a good choice but perhaps some solace in that the RWL is probably based on 8:1 or 10:1 and that they have been there a long time. I do worry that we may see a few failures as folks change to LED - which nearly is between 1.5 and 2 times the weight if you replace 1 for 1.
