I've wished for on/off stock lights to use for a while, and I loved replacing my old method of turning off lights (a reflectivity_10b material covering the light) with these props. I liked the honesty about improper baked lighting, and I can make decisions knowing the prop's weakness in total darkness.
Only the large florescent farm lights (which lack the 55 variant) I deemed not convincing enough without a new AO and stuck to my old method for that prop. The smaller lights look great in practice and even have higher texture quality. I would love to see more lights in this style.
