ANSI stands for “American National Standards Institute,” which is an organization that develops standards for a wide range of commercial products. In lighting, ANSI codes have particular relevance to common types of light bulbs, but they are less and less common in the modern lighting world.
What does ANSI code mean?
American National Standards Institute codes (ANSI codes) are standardized numeric or alphabetic codes issued by the American National Standards Institute (ANSI) to ensure uniform identification of geographic entities through all federal government agencies.
What is ANSI S55?
ANSI S55 – 4 Tap – Power Factor 90% – Max. Temp. … For use with 150 watt lamps, this magnetic HID ballast boasts a high power factor of 90%, ensuring maximum efficiency.
Does a metal halide bulb need a ballast?
Metal halide (MH) ballasts are required to start the lamp, regulate the lamp starting and lamp operating currents, and provide appropriate sustaining supply voltage. … MH lamp voltage typically increases over time, and the ballast must continue to provide sufficient voltage to the lamp as it ages.
Can you replace sodium bulb with LED?
While upgrading to LED provides a lot of benefits, high pressure sodium (HPS) lamps still provide some of the most efficient lighting available. … LEDs, however, are better able to control their light, which is why a lower-watt LED can replace a higher-watt high pressure sodium bulb.
Can I put a metal halide bulb in a regular socket?
Like fluorescent lights, metal halides require a ballast to provide high starting voltages and to regulate current inside the bulb during operation. … This is why a metal halide bulb will not work in a standard household lighting fixture — aside from the fact that the larger E39 base will not fit.
What’s better HPS or metal halide?
HPS is about twice as electrically efficient as metal halide. Photosynthetically Active Radiation (PAR) is what really matters to plant growth, and delivery of usable PAR is better with HPS than metal halide. The enhanced blue in metal halide does not lead to increased plant growth compared to HPS in the “veg” stage.
Can you touch metal halide bulb?
Yes, it’s going to be a problem for you. When the bulb is in contact with something that point on the bulb becomes a heat sink and the glass temperature on that point of the bulb will become unstable and may cause the bulb to burst. It’s the same reason that you don’t want water to ever touch a MH in operation.
