A Luminaire includes the lamp:
Luminaire. A complete lighting unit consisting of a light source such as a lamp or lamps, together with the parts designed to position the light source and connect it to the power supply. It may also include parts to protect the light source or the ballast or to distribute the light. A lampholder itself is not a luminaire

410.6 Listing Required. All luminaires and lampholders shall be listed.
Also, 410.5 prohibits live exposed terminals.

So it appears to me that this does not conform to NEC requirements.
He is not violating 410.5 since he is insulating the terminals.

I agree he is modifying the luminaire which would require AHJ permission, at least in a legalistic way.

If the bulb you chose delivers a higher color temperature or better CRI value by using UV emitting diode(s) in combination with phosphor(s) there may be excess UV emission when you remove the UV-blocking globe. This could be a serious problem, even at a distance.

So now I can turn people in for changing light bulb without a permit or electrician.

You're in Oregon; the Building Codes Division explicitly says on their website that a permit is not required to replace a lamp. But the NEC still says that the lamp must be listed.

It seems to be a thought in some quarters that there's a 1:1 correspondence between the scope of what electricians work on, and the scope of the NEC. That's not the case. Most of Chapter 8 covers subjects that in most jurisdictions don't need a permit, and are not typically performed by licensed electricians. But, for example, people like satellite dish installers must still follow the NEC.

Funny the couple type A lamps I have where the diffuser has broken off are WAY MORE DIRECTIONAL. The diffuser obviously spreads the light out more evenly but without it, it's like a spot light. Not better or worse, just different.

I have a high power LED headlamp that has a diffuser on it that can flip up, so the square LED is exposed with just a clear cover over it. The light that comes out of that, when shining on a wall, is a square beam. Nothing wrong with it, just as you say, different…
