    LED Low Pressure Sodium Replacement Bulbs

    Traditional high-intensity discharge low pressure sodium lamps produce a very yellowish light from a very narrow region of the visible spectrum. LED replacements for SOX light bulbs can replicate this color temperature, but are also available in 5000K options. These low pressure sodium replacement bulbs are often used in tunnels and on bridges. LED versions have a much better color rendering ability than traditional lamps.
