9 watt LED Medium Base Bulb FAQ
Q1. 9 watt led bulb equals how many watts?
A: According to the market general 80-90lm/W luminous efficiency, can replace 60W-80W incandescent bulbs, instead of 12-18W CFL bulbs. IMPRESS high luminous efficiency 9W LED bulbs, using 140lm/w LEDs, can replace more than 90 watts of incandescent lamps or 18 watts CFL lamps.
Q2. How many lumens is a 9w led bulbs?
A: General market circulation of 9 watt LED bulbs are 800-1000 lumens. IMPRESS 9w a21 led bulb lights up to 1200lm.
The luminous efficiency of the led beads used in the lamps, the input of different currents will make the led have different luminous efficiency, often reduce the power supply current than the full power supply luminous efficiency is higher. The same power, high luminous efficacy of high brightness.
Luminaire internal led series parallel connection form. Luminous efficiency of the same led, parallel connection number less and series connection more, requiring a smaller input current, this time even if the input current is small, but the led beads more brightness will be higher.
Q3. How to check led light bulb with multimeter?
A: Ordinary LED beads good or bad, can be directly measured by a digital multimeter. The specific method is to select the multimeter to the diode file, without this file can be selected 200Ω This file, with a meter directly in contact with the diode poles, if you can see the diode emits a faint bright light, prove that the diode must be good, if you can not see the light, prove that the diode may be abnormal, or infrared light-emitting tube.
Finished LED light bulb, excluding the detection of LED beads good or bad, but also must detect the drive power components and wiring is normal, the power supply is normal, all normal premise, the LED light bulb will glow.
