- Lamp efficacy
Lamp efficacy
By switching from mercury MBF 125 lanterns to five EP 145 LED, power use has been reduced, while the state-of-the-art LED system has increased light output.
- Ballast classification
Ballast classification
Controlling the electricity supply to the lamp (Energy Efficiency Index).
- Luminaire distribution
Luminaire distribution
Controlling light emission using optics which bend and shape the light to the correct location.
- System efficacy
System efficacy
Optical and thermal control within the luminaire are essential as even two lanterns containing the same LED module can have widely differing light output ratios (LOR), lifetimes and colour performance. EP 145 LEDs design achieves a strong LOR and therefore minimises light loss.
- Presence/absence detection
Presence/absence detection
Presence: Lights automatically turn on/off with movement. Absence: Lights automatically turn off and must be manually switched on.
- Daylight detection
Daylight detection
Artificial lighting which responds to the natural light conditions.
- Constant illuminance
Constant illuminance
A function designed to produce correct light levels for the duration of the maintenance period.
- Task-scene setting
Task-scene setting
Bi-power dimming allows light levels to be reduced during the quietest hours of the night. Automatically reducing light output and energy use by 50% for 8 hours per night results in significant energy savings with minimal impact on pedestrians and users.

Timed off
Automatic cut-off can be installed to turn all lights off during unoccupied hours.

新EP 145 LED为法国古街革新照明并大幅削减能耗。
EP 145 LED是一款19世纪风格的传统路灯，如今配置LED光源，构成耐用、节能的解决方案，用于翻新历史感厚重的街道和空间照明。
日前，法国莱桑代利的一条街道进行了翻新测试，用5盏EP 145 LED灯更换5盏老化的19世纪风格水银MBF 125路灯，目标是提高照明质量并降低能源消耗。
该计划成功实现目标，平均照明度从4.3 lux提高至11.2 lux。在双功率夜间可调装置的辅助之下，能源消耗也从原来的140W降低至28W。新灯具的使用寿命长达7万小时（@ L70 Ta 25°C），几乎不需要按常规更换灯具。
项目经理Corinne Delor解释道：“除了改善灯光质量，降低能源消耗，设计的连贯性也是这个测试项目的一项重要考量。EP 145 LED革新了技术，又保持灯具的设计维持原状。这意味着城市翻新可在街道上逐一开展，而不会出现任何不协调状况。”
“关键是维持了白色灯光，同时感觉很舒适而没有眩光。显色指数也从50增至70，这对在灯具所在的环境营造生动气氛尤为重要。”
拉桑代利市政当局表示：“这款新LED灯在光强度和照明氛围方面比以往有所改善。”来自BLONDEL的本地承包商补充说：“EP 145 LED的传统美学与这条古街完美匹配。良好的显色性让灯光的质量也有改善。而灯具在长时间内都不需要进行维护，这也是件好事。”
