NEC 314.16(C)(2) allows for splices and connections to be made in a conduit body.
An apartment complex, desiring some parking lot lights, used 2" SLB's as a means for mounting the lights. This was done by drilling and attaching the fixtures to the sides of the bodies. Of course, LB's have two openings...see how the extra opening has been covered with tape?
FWIW, there exists an "E" body, which has only one opening- though getting one this large is a problem. Or, perhaps a "tee" body could have been used, with reducers.
the other thing it do get my attetion with quatz halogen lights the T-3 or T-4 bulbs are not designed as to run off axis of horzontail due the heat build up and it will cause early bulb failure there.
I did see it many time when some handyman do this set up and burn up the halogen bulb rather very fast
and the other thing with this size of fixure it is commmon to overwattage it espcally if fixure is rated for 300 watt and it is common i did see some people jammed 500 watt halogen bulb and do wonderful damge from overheating
Pas de problme,il marche n'est-ce pas?"(No problem, it works doesn't it?)
Rad...that's an interesting point....some would also object to the use of 2" RMC as the light pole, for the same reason. I don't know how far you can go with that logic...looking at various standards, they are a lot less specific for something like an LB (for which the final use is unknown) than they are for, say, a mig welder.
FrenchE, I didn't know that...one of the problems with this installation is that the conduit nuts don't do a very good job of securing the light in the direction they want to point it.
