Is there a minimum distance between the high CRI fluorescent bulb and the work surface?

Is there a minimum distance between the high CRI fluorescent bulb and the work surface? Will your fluorescent bulbs work in an existing dimmable fluorescent fixture?

Generally speaking, we do not advise any particular minimum distance between the light source and the target. Though we can confirm that the overall lux will reduce the further the light source is from the work surface due to dispersion. 

Unfortunately, our T8 LED Tube Lights are not compatible with dimmable fixtures, and we do apologize for any impact this may have on your purchase planning. 

As alternatives that are dimmable, you may be interested in our LED Strip Lights such as the 5000K CENTRIC DAYLIGHT™ LED Strip Lights and 5000K ABSOLUTE SERIES™ LED Flexible Strip.
