The cost of LED illuminants can greatly vary, although these lights look almost similar in form. There can be as much as 40% variation in prices between LED lighting panels, despite the similarity in appearance between the illuminants and the fact that these are powered by LED (Light Emitting Diode) technology. A wise customer has to be attentive to all the important components, and have a proper idea of how they can impact the full cost. While a low price should not be the sole consideration for a LED panel light, buyers have to be more attentive to the important factors. There are various factors on which the cost of a LED panel light depends:
- LED chip
In an LED panel light, the LED chip happens to be a vital component. It stands for the highest percentage of the entire expense. The market abounds in many models and the costs can widely vary as per the bracket of packages and the waiver that is offered. While it is normal for you to find two chips that come with the same amount of waiver, the variation in costs can be in the range of 10 – 20%. The gap in price can destroy a business when it comes to bulk buying. But with the development of technology in the last few years, the cost of LED chips is constantly reducing. This has led to a drop in the total expenses of the finished panel lights.
- LED housing
It is just the external appearance of the panel light. The price varies as per the materials and the structure. Generally, the more basic the structure is, the lower the price is. The same also applies to its size. The cost is directly proportional to the size. When it comes to the materials used, LED housing made of aluminum is significantly costlier than plastic housing.
- LED driver
In an LED panel light, the LED driver happens to play a very significant role. It can have a big impact on the product’s lifetime. The cost of LED drivers can significantly vary due to the varied circuit schematics. This is applied for changing the input DC or AC to DC power for driving the LED chips. Such a mode is possible in 3 ways – isolated switch-mode, non-isolated switch mode and non-isolated linear mode.
The isolated switch mode comes with low safety risks, and is the ideal LED driver mode for this reason. It can operate in superior reliability and efficiency when it comes to light delivery. The high price is the only con. The cost of the non-isolated switch mode is comparatively low. It is highly efficient and the light distribution is very reliable. But there are security risks with this mode. The most inexpensive mode is the non-isolated linear one, which comes with a few disadvantages. It has low reliability and the security risks are high. The operational efficiency is on the lower side, and there is no optimal energy efficiency either.
