Lighting Retrofits

Lighting retrofits are defined as any change to a fixture’s components that make the fixture more energy efficient.  These upgrades are normally so significant to the energy consumption that they provide a return on the investment.

Star Energy Management specializes in lighting retrofits and will work with our clients to ensure they have a lighting plan that will meet their needs.

  • Custom design capabilities for unique applications
  • Complete understanding of the proven options available in today’s market
  • Experience in cost effective approaches without compromising quality
  • T12 – T8 Conversions
  • T8 – T8 Conversions (from an older version T8 to a more energy efficient T8)
  • Reflectors to maximize light output
  • Metal Halide, High Pressure Sodium, Mercury Vapor Lights – Convert to T8 of T5 High Bay Fixture
  • Incandescent Light Bulbs – Compact Fluorescent or LED Lights
  • Fluorescent Fixtures to LED Fixture

Fluorescent Lamps – a type of lamp that uses electricity to excite mercury vapor in argon or neon gas, producing short-wave ultraviolet light.  This light then causes a phosphor to fluoresce, producing visible light. Fluorescent lamps are much more efficient than incandescent light bulbs of an equivalent brightness because in an incandescent bulb, more energy is converted to heat rather than to usable light.  Fluorescent lamps also have a long life.

Example of the savings from a typical T12 to T8 fixture conversion:

  • Old – Fluorescent 8′ Strip Fixture with 2 8′ T12 Lamps (with Old Magnetic Ballast) = 128 watts
  • New – Fluorescent 8′ Strip Fixture with 2 4′ T8 lamps (with New Electronic High Power Ballast) = 76 watts
  • Retrofit Process for above fixture conversion – Remove two 8′ T12 lamps and install two 4′ t8 Lamps and 1 universal voltage high power ballast and 2 white ballast covers.
  • Cuts Energy Consumption by 41% per fixture

High Intensity Discharge (HID) Lamps (Mercury Vapor, Metal Halide and High Pressure Sodium)  produce a large quantity of light in a small package but have a long warm-up period to achieve full light output.  For example, if used in a school gym they are turned on in the morning and off at night, even though they may only be needed for a couple of hours during that time.  These are being replaced with the more efficient high bay fixture.

High bay fixtures are used to replace High Intensity Discharge lamps.  They produce high levels of light, but have the versatility of turning off when not in use and on when needed.  Their warm-up time is inconsequential because they are equipped with an instant start ballast.  High bay fixtures are ideal for commercial buildings with high ceilings and in applications where an occupancy sensor is used (warehouse, gym, etc.).

Typical HID to High Bay Fixture Conversion:

  • Old – 400 watt Metal Halide Fixture = 448 watts
  • New – 6- Lamp T8 Fluorescent System – 228 watts
  • This maintains the lumen levels while reducing fixture input watts
  • Cuts Energy Consumption by almost 50%

Light Emitting Diodes (LED) is the next advancement in lighting.   An LED is a semiconductor device that emits incoherent narrow-spectrum light when electrically biased in the forward direction. Their benefits include: tens of thousands of hours (if used at a rated current), no flicker (like with a fluorescent light), they are impervious to heat, cold, shock and vibration, and they have no breakable glass. The color of light that they produce is dependent upon the type of semiconducting material used, and can be near-ultraviolet, visible or infrared.
