Frequently Asked Questions
Are these lamps suitable for marine environments?
Yes, high pressure sodium R-bulb lamps are commonly used in marine applications due to their high efficiency and long lifespan. However, to ensure proper operation in salty and humid conditions, they should be used with a suitable IP65-rated marine fixture.
What is the color temperature of these bulbs?
High pressure sodium lamps emit a warm yellow-white light with a color temperature of approximately 2000K. This is ideal for outdoor and security lighting where color rendering is not critical.
What base types are available?
These R-bulb lamps are fitted with standard E39/E40 (Mogul) screw bases, compatible with most industrial marine fixtures. Always check your fixture compatibility before purchasing.
Can these bulbs be used in enclosed fixtures?
Yes, they are suitable for enclosed fixtures that provide adequate ventilation. High pressure sodium lamps generate heat, so ensure the fixture is rated for the wattage and permits heat dissipation.
