What is the application problem?
The fact is that the design of a conventional LED lamp includes a micro-rectifier, which converts the alternating voltage of 220V into a constant voltage. This device has only two positions for adjusting the light - turn on and off. At the same time, the dimmer allows you to smoothly change the illumination in the range from 10 to 100% 
. As you understand, when trying to combine ordinary light bulbs and a conventional dimmer switch, you can not achieve the desired result. In addition, in this case, both devices will fail. At the same time, the LED device for the dimmers includes an additional unit, so that the adjustment takes place.
With a view to distinguish ordinary products and dimmable it is impossible.externally they are absolutely identical. The only difference is the inscription, the improved model should have the designation "dimmable" or the corresponding logo( as shown in the photo).
What should I consider?
A very important nuance that you should know - not all dimmers are suitable for diode light bulbs. Before buying, you must always consult the conformity of both products. 
Also it should be noted that when buying lamps, it is necessary to give priority only to quality products. It is best to use dimmable LED lamps from manufacturers such as Gauss, Osram, Philips, X-Flash and Uniel. The prices of such firms are much higher, but they will last much longer.
In addition, low cost of products can be one of the reasons that the LED lamp flickers. In this case, you still have to overpay for the purchase of a new device.
Do not worry about whether the socle of the chosen bulb is suitable for a crystal chandelier installed in the house, spotlights or spots. To date, all the most popular types of lamp caps are used to manufacture dimmable devices. Normally, the bases with the markings e14, e27, GU 5.3, G9 and mr16 are suitable for luminaires. 
Well, the last, no less important advice for you - choose the right dimmer power. Each device has its own technical characteristics, which should be selected based on the total power of dimmable LED lamps. For example, if you buy a dimmer switch of 100 W, and the total power of the light sources is less, nothing good will come of it.
controller Is it worth buying?
It is very much interesting to many how a good option is to use dimmable LED lamps for the home. If you decide to apply this option only for reasons of economy, well read the reviews on the forums. Those who have already bought the products leave both positive and negative feedback.
We recommend that you use dimmable LED lamps only in order to make a cozy and unusual atmosphere in the house. The regulation of lighting will make both a muffled light for a romantic dinner, and a bright light for cooking( if you take the example of a kitchen).
The only but significant disadvantage of light bulbs is a high price, so it's good to analyze how profitable this option will be for you.
That's all I wanted to tell you about this issue. We hope that now you have completely learned what dimmable LED lamps are and how they work!
