De Doming

What is the idea behind this practice ?, how is it best done ?, has anyone who’s done it regretted it ?
Any input very appreciated, I have a few lights I may experiment on depending on people experiences of this, thanks

Having looked at the posted beamshots I defo like the domed ones more so won’t be doing this anyway now that I’ve seen the results.
