That is the 250W Powerlite Devices mercury bracket which is the same type as this Sylvania GTE S5-75B here and a close-up here . This is the one I want to switch with the restored Douglas P.P. that is now 100W metal halide. Also I received the 100W mogul base metal halide lamp today for the Douglas P.P.
Ah okay. I thought you were replacing the 250W MH Vanguard. That's staying up then? BTW, is that actually how bright it is or is it a little dimmer? Because this looks as bright as a 70W PSMH or something.
Ah actually yes the Vanguard 250W is going to be swapped with a Landmark 313 style cobrahead. The merc is pretty bright, but in the pic some of the light from it is blocked by a tree. @ Devonte, yeah hard to say how long they will last,I hope they will last a long time.
No, it's open, it has a "roll over protective structure" (ROPS) that a canopy option can be mounted to though but I never bothered to add one , someday I would like to have a tractor with an enclosed cab to be able to work in all weather.
I could think of a lot of uses for these....I wonder how the longevity on them is though.
