LED Bulb Shopping Guide
2 months ago
With online shoppers now using more and more options, you may be confused or unsure which one is the best choice for choosing a new LED investment. There are many different options, such as lumens, wattage, beam angle, color rendering, etc. You might wonder why I can’t pull my bulb out of its power (watts) and finish, if only life can be like that . easily. Well, the EU’s excellent old people have implemented a directive (2009/125 / EC) in their wisdom that requires all lighting labels to be lumens rather than electric tiles since September 2010. You may want to know why they did it. The good question, in simple terms, is that Watt is not a useful comparison of LED brightness versus brightness. The higher the lumen, the brighter the light. Therefore, always consider the lumen output of any bulb you are purchasing. For example, a candle has about 13 lumens of light; a 60 watt incandescent lamp emits 720 lumens, the brighter the light source, the more lumens.
Take today’s LED technology (led lampor) as an example, we get 100 lumens per watt. The 4.5 watt LED = 450 lumens compared to a halogen lamp that produces about 12 lumens per watt.
Now, in the next question, can I replace the existing lights with my home LED?
The good news is that most new LED bulbs can be replaced without problems. Find the right bulb base, choose the type of lumen you want, color temperature (eg warm white, pure white), then leave. This moment is not so easy.
Visit some popular LED websites, including a light bulb image menu, which allows you to easily select the right connection before purchasing.
Next option – adjustable or not adjusted?
Like your old light bulb, the LED light can be adjusted, but it will only be adjusted when it is marked on the website/package. Most likely, you will need to pay more for the adjustable version of the LED bulb. The choice is because this feature requires some extra components. Another important point to consider is: Do I need a new intensity regulator, or is my current regulator sufficient? The answer is simple: you may not know, it may be that your existing dimmer has been around for a few years and is not compatible with your new adjustable LED bulb. You need to install a dimmer switch on the trailing edge to ensure the life of your new investment. So I suggest you not to buy a new dimmer switch LED.
Although we are talking about the attenuation problem, if you buy a 12 volt LED bulb, the old or existing transformer may not be compatible, which may be due to the nature of the bulb. It will have LEDs and sensitive internal circuitry. You need a driver / LED transformer to provide constant current (electrical terminology) so that the LED bulbs (led lampor) work properly. Similarly, it is a good idea to replace the transformer with a new LED. Keep in mind that you can use a larger LED power controller to work at multiple LED points without having to buy a small LED driver for each bulb.
The color temperature, or the color of the simple light, will extinguish the bulb.
The answer here is simple:
Warm white is an ideal complement to traditional halogen or incandescent bulbs, producing a warm yellow light with a color temperature of 3,200 K (possibly also used by most people).
Pure White produces white light, which is often used in commercial environments or creates a very modern look with a color temperature of 6500K.
When viewing your product online, you may notice that the numbers they quote are the same as the numbers above, which means that there is a high K number at the end. This is just the color temperature output in the Kelvin unit (K). Some websites will show you a beautiful table with a color temperature ranging from warm white to cool white and Kelvin scale, which is very useful because it indicates the possible output.
