Sylvania 67533 – Frequently Asked Questions

1) Do I need a ballast for the Sylvania 67533 400W HPS lamp, or can I wire it direct?
This is a high pressure sodium HID lamp, not an LED or incandescent replacement. It must run on a 400W HPS ballast and ignitor matched to the lamp wattage. Putting it in a metal halide or mercury vapor fixture without changing the ballast will not work.
2) What color is the light from this Sylvania HPS lamp, and is 22 CRI good enough for my application?
2100K with a CRI of 22 means the classic amber-gold HPS light. Colors will not read accurately under it, so it is wrong for retail, inspection work, or anywhere color matching matters. For security lighting, roadways, storage yards, and warehouse aisles where you only need to see shape and movement, it is the normal choice and the long-range penetration is part of why.
3) Can I use the Sylvania 67533 to replace a 400W metal halide lamp in the same fixture?
No. Metal halide and high pressure sodium run on different ballast circuits, and an HPS lamp needs an ignitor the MH ballast does not supply. The 67533 is strictly a replacement for an existing 400W HPS lamp on an HPS ballast with an E39 mogul socket.
4) How much light does a 400W HPS lamp actually put out for a parking lot or warehouse?
The 67533 is rated 50,000 lumens at 400 watts, which is why 400W HPS has been the workhorse for parking lots, roadway, and industrial high-bay. That output covers large open areas from pole or high-bay mounting heights with relatively few fixtures.
5) What is the Sylvania part number and series for this 400W HPS lamp so I can standardize across my buildings?
Order it as Sylvania 67533, the 400W ET18 lamp in the Lumalux Ecologic HPS line. Keeping one part number across all 400W HPS fixtures in a portfolio means one spare on the shelf and consistent 2100K color across every pole, which matters when half a lot is relamped at a time.
6) Is the Sylvania Lumalux Ecologic the same thing as the Philips Ceramalux Alto?
They are each manufacturer's own HPS lamp line, not the same product family. The Sylvania 67533 belongs to the Lumalux Ecologic series and is a 400W ET18 lamp rated 50,000 lumens at 2100K with 22 CRI. The Philips Lighting 467241 belongs to the Ceramalux Alto series and is a 100W ED23 lamp. Both carry an E39 mogul base. If a facility is standardizing, keep the series consistent across fixtures of the same wattage rather than assuming the two names cross-reference.
