Proposed Product Specifications

We have had many requests regarding the proposed performance of the Vu1 ESL R-30 bulb.  The following specifications are those that we have established with Vu1’s engineering and manufacturing groups for our first product.  Some of these specifications have already been met.   Final published performance to these specification will come from independent lab testing, formal certification reporting and through product safety testing that will be conducted by groups such as UL and ETL.   These are the TARGET specifications that Vu1 is currently working toward.

Vu1 ESL R-30 Reflector Bulb

Product Description

Vu1's first consumer product will be a reflector bulb in the R-30 shape.  The R-30 is the predominant bulb utilized in recessed can lighting applications.    R lamps designed for use in places such as showroom floors, museums and for general overhead lighting in homes where a smooth distribution of light with a soft-edged beam is desired

Product Specification (proposed)


The Vu1  R-30 will be a direct replacement for any R-30 incandescent reflector bulb.  In shape, size, and performance (illumination, light color, dimablity, instant on) the Vu1 ESL R-30 will be indistinguishable from an incandescent R-30.
