This life span is a value calculated based on the strength of adhesion in the high-temperature, high-humidity acceleration test for durability of this product. The life span of each product using this product as a material differs from this life span.
The production efciency of an evaluation product is calculated on assumption that the production efciency of conventional products under the recommended adhesion time (20 seconds) is 100.

The adhesion temperature is a temperature where the product is pasted to the base material. Pitch means the maximum number of electrodes (denition) that can be connected in batch.
Reason for reduction: Production cost reduction due to improved productivity.
Reason for reduction: The amount of materials is not reduced because the same materials are used.

This high-performance lamp has a ceramics arc tube that can be turned on through the regular mercury-vapor lamp ballast.
The electrical charge is halved, maintaining the same life span and almost the same brightness. Manufactured in 2000

The rated life span (hour) of lamp is calculated, assuming that the daily lighting time is 10 hours and a year is 365 days. 12000 (hours)/(10(hours/day) x 365 (days/year)) =3.3 year The lighting direction and lighting conditions conform to descriptions given in the JIS C 7604-1999 High pressure mercury lamp. Performance (Im/W)=All luminous uxes (Im)/rated lamp power (W) Lighting takes place through the 200V regular ballast with a high power factor. Input voltage of base product: 0.415kW Input voltage of evaluation product: 0.208kW Annual lighting time: 3,650 hours (10 hours x 365 days) Input power measurement takes place in accordance with descriptions given in the JIS C 8110-1987 Mercury lamp ballast and low pressure Na lamp ballast.

Reason for reduction: Power consumption has been halved, maintaining the same brightness.
Reason for reduction: The product mass decreases by 30% and the product volume by about 50%.

The product life span depends on the lighting instrument replacement timing dened by the Japan Luminaries Association. To determine this efciency, all light uxes are divided by the power consumption per hour because of the system product. To determine mass efciency, all light uxes are divided by the total weight of system (all component products). Refers to the total power consumption of the system installed in a shop. All system: 365 working days/24 working hours/day length 5 hours/day (with 2-hour clear sky)/constant illumination intensity based on average dimming rate. Indoor illumination: 24-hour lighting/daylight/timer-controlled method/ dimming pattern. Parking lighting: 13-hour lighting/stepwise dimming 7 hours/delay 2 hours. Signboard lighting: Lighting takes place 30 minutes before sunset through the solar timer based method.
Reason for reduction: Control circuits are added to more efciently control lighting facilities in shops, signboards or parking areas.
Reason for reduction: An instrument section has been slimmed in the main lighting equipment designed for shops.
