These look nicely made. Substance painter certainly makes it easier to texture things quickly
What platform will you be running your game on? I feel like the triangle count may be too high for smaller props like these, especially when you have to load a bunch of these on screen at once. For example, I have used a similar lamp for a mobile game in an office map, and I dont think it exceeded 500 tris. It was also placed several times along with similar types of props that match it, like desks, chairs, paper piles, computers, and many other things. From a mobile game point of view, I find tri count can get out of hand real quick once you start populating a scene.
