RE: DIY Sun Gun
A little backround-

Colour rendering index (CRI)
A scale of the effect of a light source on the colour appearance of an object compared to its colour appearance under a reference light source. Expressed on a scale of 1 to 100, where 100 indicates no colour shift, a low CRI rating suggests that the colours of objects will appear unnatural under that particular light source. CRI is a unit of measure that defines how well colours are rendered by different illumination conditions in comparison to a standard (i.e. a thermal radiator or daylight). CRI is calculated on a scale from 1-100 where a CRI of 100 would represent that all colour samples illuminated by a light source in question would appear to have the same colour as those same samples illuminated by a reference source.

The SunGun's lamp has a CRI of 90-95 (sunlight CRI 100)

So if you're comparing like with like what is this lamps CRI?
