In fact they re roughly as efficient as leds in terms of their light output for each watt of energy used.
Can you put a high pressure sodium bulb in a metal halide fixture.
Their operation is a bit different and they therefore require different ballasts.
No metal halide lamps require the electrical operating characteristics that the associated metal halide ballast produces.
Fixture is the word to describe what the lamp goes into.
Does that mean that i can t or shouldn t replace the original 70 watt hps with say a 100 watt bulb assuming it was the same size and would.
Stick the hps stuff in the bin and invest in an icecap.
And in your case you need not one but two special fixtures.
High pressure sodium bulbs lamps are an old standby for lighting that s still used today in spite of so much talk of led lights.
But the converse is not true.
While upgrading to led provides a lot of benefits high pressure sodium hps lamps still provide some of the most efficient lighting available.
A high pressure sodium ballast also is equipped with an igniter used to.
A high pressure sodium lamp requires a ballast to operate and a metal halide.
Whilst you can stick the lamp with the hps sodium gear you will not get the correct colour temperature due to lamp not being at correct operating temperatures and you will drastically shorten the lifespan of it.
In practice we have used sodium vapour ballasts for metal halide lamps without problems for years.
A high pressure sodium bulb produces light that is reddish yellow while metal halide bulbs produce a much more balanced white light that has more of the visual spectrum.
Light like maybe a metal halide bulb or is the ballast in this fixture specific and can only with with high pressure sodium bulbs.
A high pressure sodium ballast also is equipped with an igniter used to.
No metal halide lamps require the electrical operating characteristics that the associated metal halide ballast produces.
These bulbs cannot be interchanged without changing their ballast the regulating element in all light bulbs.
The ballast is specific to the type of vapor and wattage.
