This is on next weekends agenda, I just need to get my wife a new drier then the old one is mine , good timing as well, as all my products and machine will be here so I can use the light too.

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?

What a clever idea.

Thanks for the link Onyx.

I've gathered all I could to build one: a dead hair dryer, a 5 watt LED bulb and a base

I was advised by a friend to use the LED bulbs instead of the halogen bulb. more light, longer durability and less heat.

Excuse me for the quality of the pics my photography skills not fine tuned and it's the camera phone, it doesn't capture all that we see.

Still the difference is evident.

Thanks pal

My 1st try with the home made sun gun was in the early dawn (everybody else sleeping )

I washed n clayed the boot lid of my uncle's Honda Civic. Note the moist, it was difficult to see the swirls under the fluorescent tubes. With the Led, it was clear.





After a few compounding passes



I set to work then.
in the shade, the compounded section was superb but in the sun, the holograms were obvious.

I didn't have to polish it after. The car was sold.

If you are trying to build one, try compare a 10 watt LEd bulb with a 5 watt.

Nicely done!
Swop that with the wifeys hair dryer and have a laugh
