Background
WD need to reduce energy. The LED for fluorescent instead is one solution for help to reduce energy. There can save energy 50% per bulb. Now we use so many fluorescent about 30,000bulb for all WD bangpa-in. The LED is new technology lighting.
Scope of Work Requirement:
1. Change fluorescent lamp to LED total 30,000 bulb include labour cost and modify for compatible lighting fixture and circuit.
2. LED fluorescent spec as below.
a. Energy consumption 100 lm/W.
c. Life time > 50,000 hours.
d. Warranty >5 year (Need to change bulb only)
e. Maximum color temperature = 6500K
f. CRI >75
g. COB shell be advantage.
3. Calculation sheet report for energy saving cost and luminaires.
4. No discomfort to the eyes.
5. Can use in clear room and no ESD effect.
6. CE & TIS certificate at least.
7. Measure luminaire all area every 3 months for 1 year.
If brightness drop more than 1 % for 1 year, replace new bulb.
