T5 Lamps
From Swikipedia
Introduction
Designed in the 1990s, T5 lamps are the most energy efficient lighting technology obtainable in the fluorescent lighting industry, that use 45% and 12% less energy than its T12 and T8 predecessors.
Brief Description
T5 Tube lights:
With a diameter of 16mm and length 50mm, T5 tube lights are shorter in comparison to standard T12/T8 system. Their use allows the tubes to be fitted into smaller spaces, (such as modular ceilings, modular cupboards, etc.), and the smaller light source also enables more accurate control of beam direction by means of optics (reflectors and lenses in the luminaire).They too, require ballast & lamp to be installed. Their efficiency can go up to 105 lm/watt.
Benefits:
- These lamps can be used to grow mature indoor plants
- T5 lamp provides peak light output at 35 °C (95 °F) air temperature. (By contrast, the T8 and the T12 lamps provide peak light output at a 25 °C [77 °F] ambient air temperature.)
- It has a higher lumens-per-watt efficiency than a T8 lamp of about the same wattage, in a space where there is little or no air circulation
- T5 lamps are a popular energy-efficiency measure, due to their potential to cut energy use in lighting by more than 60%
- T5 lamps generally last for 20,000 hours, as compared to T8 lamps, which last for 15,000 hours.
