However there is exactly one other type of lighting that beats hps in that category and that is light emitting diode led.
High pressure sodium lights to led.
High pressure sodium hps lights are commonly used for outdoor application like parking lot lighting street lights etc.
High pressure sodium hps parking lot lighting led parking lot lighting fixtures a led light bulb generates light by constant movement of electrons.
High pressure sodium lights have long warm up time usually around 15 20 minutes.
Indeed high pressure sodium hps lights are generally unmatched in terms of energy efficiency.
Led area lights are top of the line bulbs.
Led lamps produce light of a much higher quality as opposed to the dim yellow one generated by hps.
While upgrading to led provides a lot of benefits high pressure sodium hps lamps still provide some of the most efficient lighting available.
As indicated by the name high pressure sodium vapor lights operate at a higher internal pressure.
The principal difference between low and high pressure sodium lights is the operating pressure inside the lamp.
The popularity of that technology is not just due to its energy efficiency.
High pressure sodium hps lights similar to lps lights are a specific type of gas discharge light also known as a high intensity discharge hid or arc light.
High efficacy that is easily comparable to led lights.

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.
Leds last longer than any light source commercially available on the market.
Hps lights have good lifespans around 14 000 hours though this is significantly less than leds.
High pressure sodium lights range between 5 10.
Led fittings are instantly at full output.
