Just that LPS won't be around much longer becuase the LPS lamp manufacturing plants are closing.Also Ceramic Metal Halide is another contender LED has to compete with-its like a horse race-one gets neck-to-neck with the other and so on.I use CMH at home and LOVE it!CHM is mostly used for indoor lighting.There are CMH retrofit-conversion lamps that you can use in HPS fixtures and ballasts-this give the HPS light the nice WHITE light instead of amber color light.The lamps are available from Philips and GE.Venture makes a pinched quartz arc tube conversion lamp for HPS fixtures.The conversion lamps area available in 250W,400W.

Philips SOX lamps

The two '82 vintage LPS lamps I have still have their Norelco branded,made in Belgium Philips bulbs,but a new Philips 18W SOX I recently bought for a N.O.S.,1999 vintage fixture was made in UK and different design than the early '80s Belgium bulbs.My LPS fixtures are my faves-nice glare free light,high "coolness"factor and low bug attraction-though at certain times of year,large black beetles are one of the few bugs attracted to the deep yellow sodium light.
