Re: Installation of 2 x 4 ft light fixtures
What test is this? I.M.H.O. siesmic of light fixtures is drvien by the following: IBC 1621.2.5, UBC 25-2, CISCA 3-4, ASCE-7. It depends on the grid system. What is the gauge of the main runners? Is it a heavy duty grid? What siesmic design category or siesmic zone are you in? I don't like that question...not enough info.
