1. The LED chip wholeslae waterproof led dot lights.The LED chip is an important component of a light. It accounts for the highest percentage of the total cost. There are many models available in the market and the prices can vary greatly in accordance with the packages bracket and the wafer. It is normal to find two chips of the same wafer but the price difference can range from 10% to 20%. This price gap can kill a business in the bulk purchases. However, with the technology developing in the past several years, the cost of the LED chip is decreasing continuously, which results in the total cost decline in the finished products.

2. The LED driver.The LED driver plays a very important part of the LED tube product. It can heavily affect the lifetime of the finished product. Due to the different circuit schematics, the cost of the drivers varies greatly. It is applied to change the input AC or DC to DC power to drive the LED chips. This mode can be achieved in three ways, namely, non-isolated linear mode, non-isolated switch mode and isolated switch-mode.

The non-isolated linear mode is cheap, but has some disadvantages. It puts an LED bulb product at high security risk with poor reliability. The worst is that its working efficiency is low, and cannot maximize the energy-saving purpose. The non-isolated switch mode of the LED driver costs relatively low. It works with great efficiency and it is highly reliable when delivering the light. However, this mode is still at high security risk. The isolated switch mode is the perfect mode for a driver, as it at low security risk. This mode can work in great efficiency and reliability when delivering the light. The only disadvantage is that the cost is very high.

The non-isolated linear mode and the non-isolated switch mode cost less but the reliability is poor, which may cause trouble during the customer’s usage. This situation will increase the cost of the after-sales. While the isolated switch mode of the LED driver does not have this problem, but it hurts at the high cost.

3. The LED housing.The LED housing is simply the outer appearance of the finished product. Its cost varies according to the structures and the materials. In general practice, the simpler of the structure, the lower is the cost. This is also true to the size. The smaller size can achieve to the lower cost. In terms of the materials, the aluminum LED housing is much more expensive than the plastic ones.

Based on the above introduction, the similar products may differ greatly from others on the prices, due to the difference of the parts. If the buyers only look for products of the low prices, it may cause unnecessary loss as the features may not meet the buyers’ needs. For example, the lifetime of the wholesale LED tube is not as long as expected. A better approach is to discuss with the suppliers or manufacturers on the products, to let they fully know the requirements of the buyers. In this way, the suppliers can proposal a good solution to buyers, and slight modification can be made on the further discussion. This practice can avoid the unnecessary loss on the purchase, as the proposals of the suppliers can meet the purchase requirement at a low cost. The suppliers will not provide low-quality products to maintain their own profits. This practice can build a win-win business result.
