Sylvania 64479 – Frequently Asked Questions

1) Can I screw a Sylvania 64479 metal halide lamp into a standard medium-base socket?
Mechanically, yes. The 64479 uses an E26 medium screw base, the same thread as a household lamp socket. Electrically it is a different story: this is a 175 watt metal halide (HID) lamp and it only works in a fixture with the matching 175W metal halide ballast and socket rating. Putting it in an ordinary incandescent or LED socket with no ballast will not light it.
2) Will the Sylvania 64479 replace the 175W metal halide lamp in my existing high bay fixture?
If the fixture is a 175W metal halide with an E26 medium socket, the 64479 M175/U/MED drops straight in. The ballast has to be 175W metal halide, not mercury vapor or high pressure sodium, and not a 250W or 400W unit. Mismatch the ballast wattage and you shorten lamp life or get no strike at all.
3) How much light does a 175W Sylvania Metalarc metal halide lamp actually put out?
Rated output is 12,800 to 14,400 lumens. The higher figure is initial output; HID lamps depreciate over life, so lay out a warehouse or parking area on the lower end of that range if you want the light levels to hold up a couple of years in.
4) What color light does the Sylvania 64479 produce, and will it match my other metal halide lamps?
It runs 4000K, a cool white, with a 65 CRI. If the rest of your bays are 4000K metal halide, this blends. It will look noticeably cooler and bluer than 3000K lamps and much whiter than high pressure sodium, so avoid mixing them in one open space where the difference is visible.
5) Can the Sylvania 64479 be burned in any position?
Yes. The M175/U/MED designation includes the U for universal burn position, so it can be operated base up, base down, or horizontal. That matters when you're stocking one lamp for both pendant high bays and wall-pack style fixtures.
6) What is the exact part number to order for the Sylvania 175W E17 metal halide lamp?
Sylvania part number 64479, ordering designation M175/U/MED, in the Metalarc Compact Super series. The E17 refers to the compact bulb shape, not the base; the base is E26 medium. Quote the 64479 number so you don't get the mogul-base 175W version by mistake.
7) Should I stay with metal halide or convert the fixture to LED?
Re-lamping with the 64479 is the fastest, lowest-cost move if the fixture, socket and 175W metal halide ballast are all healthy: screw it in and you're done. A conversion means new fixtures or retrofit kits plus ballast removal. Where the ballast is failing, or you want instant restrike with no warm-up, LED is the better long-term answer. Metal halide at 12,800 to 14,400 lumens still covers a lot of bay lighting without touching the wiring.
8) Is 65 CRI good enough for a retail or warehouse space?
65 CRI is general-purpose accuracy. It's fine for warehouse aisles, loading docks, manufacturing floors and parking structures where you need to see clearly and read labels. For retail merchandising, paint or color matching, or anywhere product color sells the item, 65 CRI is too coarse and you want a higher-CRI source.
