we have created our own brand "Vertex",Our HID xenon lamps use Anti-UV quartz glasses and American GE-6000K lamp tubes as material. We make the ballasts and bulbs ourselves. Our HID xenon lamp start very fast, in 0.8 second reach 20% brightness at about 8.5A. And market feedbacks show that our products are high efficiency and brightness.Our ballasts can automatically self-check and add power, let the lamps stay 35W 3000 Lumens. We have upgraded our ballasts to digital ones.The new ballast has intelligence functions to meet different types of bulbs performance. When the bulb voltage is AC 60-150V, the ballast can work properly. And it is wide voltage design, the intelligence ballast can work between 7.5V and 18.5V. It is less lumen loss, after the HID lifetime is over 2200 hours, the lumen still can reach 80% of new lamp brightness. And the new ballast has very good Anti-Electronic disturb function. If you are interested in any series, please do not hesitate to contact me in order to get the more information. We will offer the best quality and most competitive price to you.
