Q:What's the problem with moisture in the floodlights?
Be careful1, try to use series LED form, because the LED floodlight voltage difference is special. The peak current of the common LED is maintained at 80 Ma and the reverse voltage is up and down at 6V. In the LED application, the peak voltage and current at the limit shall be considered when designing the circuit.2, when using 25 Watt welding voltage, electric iron temperature controlled at 300 degrees Celsius in the high temperature state of SMD LED, do not squeeze epoxy resin part of it, or wipe with sharp objects, because the LED lamp is very fragile, easily damaged, welding time is 3 seconds.LED flood light is widely used, so the installation skills and precautions are very important, LED is a new light source, in the right way to install, to ensure that LED floodlight stable long-term normal work.
Q:Do you use spotlight for car led, and floodlight?
Indoor astigmatism should be better, according to a little more spacious, indoor brightness requirements are not very bright, wider, and small lights are also bright
Q:LED50W flood light is on for 24 hours. How many years can it take?
If you do not have contact, there is no impact, not too close to the good. The computer is open, easy to cause a lot of dust, the bedroom can not be put
Q:LED floodlight shell is what material? Is it corrosion proof?
Cast aluminium.Corrosion prevention depends on your environment. Usually 3 years is good for outdoor advertising. The first problem of the shell is waterproof apron. Usually, aprons are used in 8 places, such as floodlight (floodlight).
Q:What's the difference between a LED projector or a floodlight?
The difference between light and light is the projection angle of light above, but now many people confuse is not a standard to distinguish between them, why they are 2 is often used together, or can be simple to understand, cast light on his beam is unified, is also relatively concentrated source put in a building or landscape on the object, but also now he made his second astigmatism, floodlight lighting range is relatively large.
Q:The site of the gantry crane above LED can be installed floodlights or floodlights in general?
Yes, the light will be good, at least 100W, this price is uneven, you can look at the price on the internet.
Q:What's the difference between LED floodlight or HID floodlight? How many kinds?
HID flood lightThe light source is made of metal halide lamp (HGJLD) and high pressure sodium lamp (HGND) bulb. The appliance adopts the metal halide lamp inductive ballast (HGHID-Z) and the high voltage sodium lamp inductance ballast (HGNG-Z). Electronic trigger (HGCFQ-001), capacitance (HGDRQ-001). High luminous efficiency, high display and small volume. Light up, turn off the light bulb, and then cool down before you can light it up again. Cannot start instantaneously. But when the bulb or appliance is on, you can replace it yourself.
Q:LED lamp and metal halide lamp lighting height ratio, the better?
Although come to LED energy-saving lamp direction, but also has a prominent LED energy-saving lamp, that is high temperature and short service life, fast decay, need strong cooling system. At present, if we need high-power lamps and lanterns, we recommend using metal halide lamps.
Q:What are the 50 and 70 degree lenses for LED floodlights?
In this way, the lenses with smaller degrees are more suitable for areas with relatively small illumination rangeLight range is also related to the power of the lamp, power and low power according to the "at the same distance" place, certainly high power bright,
Q:Do you use spotlight for car led, or floodlight?
Indoor astigmatism should be better, according to the more spacious, indoor brightness requirements are not very bright, a little wider, and small lights are also bright light, the reason is not explained, in short, in addition to headlights, other bulbs are to diverge a little!
