SPECTRA OF HIGH-PRESSURE SODIUM VAPOUR LAMPS


This web page will be for nothing but spectra of HPS (High Pressure Sodium) lamps (bulbs).

Ocean Optics USB2000 Spectrometer donated by P.L.
As of 10-10-07, I've been using a PC2000-ISA Spectrometer from Ocean Optics that I received several years ago, but that I didn't have a home for until now.
As of 03-08-08, I once again have the USB2000 spectrometer, enabling color spectra again.
As of 09-19-09, I no longer have the PC2000-ISA; it was sold to prevent an eviction.



SPECTRA OF HPS BULBS

Spectrographic analysis
Spectrographic analysis of a HPS bulb on the front of a house across the street (I brought my laptop & spectrometer with me to perform these analyses)

Spectrographic analysis
Spectrographic analysis of a HPS bulb on the front of a house across the street; spectrometer's response narrowed to a band between 420nm and 700nm.

Spectrographic analysis
Spectrographic analysis of a HPS bulb on the front of a house across the street; spectrometer's response narrowed to a band between 585nm and 595nm to pinpoint the two sodium emission peaks at 586.510nm and 589.880nm.

My spectrometer does not have sufficient resolution to image the spectral doublet (the D-lines) at 588.9950nm and 589.5924nm

The raw spectrometer data (tab-delimited that can be loaded into Excel) is at hps.txt










Do you manufacture or sell an LED flashlight, task light, utility light, or module of some kind? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light did? If you have a sample available for this type of real-world, real-time testing, please contact me at bdf1111@yahoo.com.
