R30 Bulb Production

I am happy to report that production has commenced on the R30 bulb in China.

At this writing, I am happy to report that we have ramped up manufacturing at three key plants that are making the components that comprise the Vu1 R30 bulb. In the pictures that accompany this blog post, you are looking at the manufacture of the electron gun and the phosphor coating process – two key steps that create our near-Lambertian full-spectrum light.

These components, along with the bulb itself and some other electronics, will be fused together to make our finished product at the Huayi plant. Manufacturing equipment at Huayi is almost completely installed. A pair of proprietary processes that are critical for the Vu1 ESL — processes which ensure the durability and long-lasting nature of the bulbs – will soon be in place and allow us to move forward with final assembly.

Once final assembly is under way, we will begin to ship finished bulbs.

As information becomes available, we will update you. In the meantime, I thank you for your patience and appreciate your continued interest.

This is the gun sealing in area. The electron gun is mounted on a glass stem. The glass stem, with the gun, is inserted into the bulb. Then with a flame, the glass stem is fused, welded, melted together, into the bulb making a vacuum seal.

Bulb coating process. In this fixture, the phosphor is put into a liquid suspension and poured into the upside down bulb. The bulb is then rotated and tilted to coat it uniformly.

The inside of the bulb is coated with aluminum. The gauge on the top is used to measure aluminum thickness.

The bulbs, in the corner of the table, are drying in a forced air-drying rack.
