EXPLOSION-PROOF LAMP VS INDUCTION LAMP

COMPARISON	BEFORE	AFTER
COMPARISON
LIGHT SOURCE	Explosion-proof lamp	Induction lamp
RATED POWER	400W	200W
ACTUAL POWER CONSUMED	460W	210W
BRIGHTNESS	196 Lux	354 Lux
LUMINOUS EFFICACY	60 Lm/W Uneven light Low luminous efficacy Porr color rendering	150 Lm/W Crisp uniform light High luminous efficacy Low lumen depreciation Excellent color rendering
SERVICE LIFE	8000 hours (1 year)	100,000 hours (10 years)
AMOUNT	18 sets	12 sets
ENERGY SAVINGS	(460–210)W18 = 4500W 18hrs/day can save: 450018/1000 = 81 kWh 1year:30,000 kWh
POWER EXPENDITURE (0.11 USD/kWh)	$6,250 USD/year	$1,875/year
RELATED SAVINGS	NONE	YOU SAVE ON MANTENANCE FEES OVER PERIOD OF 10 YAERS
SAVINGS	NONE	$4,375 USD/year
RELATED SAVINGS		You save on maintenance fees for 18 sets explosion-proof lamps over a period of 10 years You save on maintenance fees for high ceiling areas (Gas stations are 5 M high)
CONCLUSION	USING A NEW LIGHT SOURCE, WHILE INCREASING THE BRIGHTNESS, BUT USING FEWER LAMPS, THERE IS AN ENERGY SAVINGS OF MORE THAN 70%, WHILE OBTANING A 75% STRONGER LUMINOUS EFFICACY
