FAQ
- What are the models of ultra high brightness LED on flashlights?
- CREE's main models are: single core -Q5, R5, these two are currently the most commonly used, the other although there are, but the size is not large, many models have been eliminated or discontinued. Q5 is the highest brightness of about 230 lumens, converging slightly better, but the heat is not small, the new R5 XPG floodlight is slightly larger than the Q5 XRE, but higher brightness, luminous flux of 350 lumens Q5 higher than one half, and high brightness driving, low fever, high light efficiency. Now more and more with the torch in hand.
- What can change the flashlight bulb?
- 1, the luminous flux of 350Lm is not completely accurate, Q5 flashlight, the top of the day will be no more than 260Lm, generally more than 220Lm will have serious attenuation;The lithium battery 2, 2800mAH, is completely nonsense, do Sony 2600mAH battery to global recall, he can do the industry second?
- The Q5 flashlight long-range rechargeable LED flashlight 14500 battery No. 5
- Battery No. 5 is at most R5, and the above T6 is not enough, just point T6, and only R5 brightness!
- Rechargeable LED flashlight can not be repaired?
- No. Unscrew the lamp cap first, then screw down, there is a screw, but you don't find the position. Is there any label paper on the flashlight? Tear and see the screw.
- LED light resistance, I use flashlight LED lights plus resistors used in the 12V circuit can be used for a long time?
- If only a single LED lamp and resistor, so voltage resistor consumes basically is 12-3=9V, working current of 60mA lamp, then the power loss of resistance to 0.06x9=0.54W, so the use of least resistance power must be above 1W, but this power is part of the battery discharge current limiting resistance loss, fever will be great
- How to install the LED flashlight lamp in the reflecting cup.
- The heat radiation of the torch is cooled by solid lamp storehouse + lamp cylinderThere are also one warehouse light bin + lamp cylinder, poor quality and cheap flashlight is a hollow lamp warehouse
- Charging time of LED rechargeable small flashlight
- The first three times will take at least 12 hours, regardless of the lightsLater, as long as the instructions are out, the lights will do
- How to detect the flashlight LED lamp is good or bad?
- It may be because the measurements in the plate, 6 beads in parallel, and the meter provide insufficient measurements of current shunting. Well, after the 2 1.5V batteries are connected in series, measure directly, or measure the resistance of the mobile phone battery string 50, or measure the resistance of the charger with a 100 ohm charger.As long as the measurement voltage is controlled at about 3V DC or the current under DC 20mA is measured, the results can be obtained directly in the plate measurementPut aside
