  • Two part numbers Carried as Neptune Benson 1000-2671 and as Delta Ultraviolet 70-18420-S, so check both against your unit.
  • Lamp only Sold as the replacement lamp, not as a sleeve or a complete assembly.
  • Output fades before the light does UV lamps lose germicidal output well before they stop glowing, which is why they are replaced on a schedule rather than on failure.

Product details

This is a 4 pin base ultraviolet lamp rated at 80 watts, carried as Neptune Benson part 1000-2671 and also listed under the Delta Ultraviolet number 70-18420-S. It is supplied as the lamp alone.

Check the number on your unit

The lamp appears under both part numbers in the source data, so match whichever one is printed on the old lamp or on the system label. The physical checks are the same either way: a 4 pin base and an 80 watt rating.

When to replace it

Ultraviolet lamps do not fail the way a light bulb does. Their germicidal output falls off steadily while the lamp still glows, so a UV system can look like it is working long after it has stopped sanitizing. Replace on the interval in your system manual, not when the lamp goes dark. When you fit the new one, keep your fingers off the glass, since skin oils on the envelope shorten lamp life.

Questions and answers

What people ask about this product, answered by our pool techs.

Why are there two part numbers?
The source carries this lamp as Neptune Benson 1000-2671 and as Delta Ultraviolet 70-18420-S. Check whichever number appears on your unit or on the lamp you are pulling out.
What is the wattage?
80 W.
What base does it use?
A 4 pin base.
How often should a UV lamp be changed?
UV lamps lose germicidal output long before they stop lighting up, so a lamp that still glows can be doing very little. Follow the replacement interval in your system manual rather than waiting for it to go dark.
