Company Information





Question 1:

In the market,I find the price for 1w high power led products has a big range,the price such as 0.182 usd, 0.298 usd, and 0.397 usd. What's the difference?
Answer:as a word saying"what price what goods",you will get what you pay for.The price is not the key,but the price can explain the goods quality.At first,the high lumen led chip is very expensive in market,and the bridgelux/epistar chip is the highest in price.Also,we need Professional worker and machine to specialize in producing. Lower price will attract buyer but we focus on the quality and promise to make customer satisfy with our products.Some manufacturer cheat the customers with low quality material or bad chip,but they have forgot honesty is best policy.If you have bought cheap led with high lumens or good brank,to have a test for it is a wise choice.

Question 2:

what's the materials in your LED products?
Answer:We adopt Epileds Chip,intematix powder,heraeus golden wire and Dow Corning silica gel.We focus on high quality products,the price is worth to pay.
Warm prompt::We only promise the quality for the led beads,not including the Effect of welding or the solidification effect.Before you weld the led bead,please take care of your led driver and gel,anything wrong without our products quality range,we won't take charge.
