why should they look different? its what's inside that matters. they operate different.
Just get everything rated for your legs, ie your cell dimmer and try it. A better alternative that will 100 percent work would be a time clock, just set your appropriate times depending the season. You can easily turn your switch into a two gang box and install it directly next to it.

A timer would be a pain to me. Every day the light changes.

What is a thermal photo sensor? How would it work in freezing weather. Photo cells are photo-electric and triggered by light waves. Maybe they have some combo units for some specialty, I don't know.

Don't know about current tech, but back in the day it used a photoresistor that let more or less current flow depending on the light level. That current would heat up a bimetallic strip, which then flexed to bring a pair of electrical contacts together (or apart).

These days, most stuff is all solid state unless it's switching some pretty hefty loads.

most are not solid state. the old thermal resistors is what you'll find in most stores. i guess its just proven old technology. but it doesnt work well with led lights and dimmers.

I never heard them called thermal before. How do they work in the winter. I thought they were sensitive to photons.

Pretty well.

It does seem counterintuitive. I never looked into it, but I imagine the bimetallic assembly would be fashioned in such a way that its range of motion with/without current well exceeds that provided by normal changes in ambient temps.

Hi..i am a new user here. As per my knowledge dimming them will can't give you the warm light you want. Mine are 350 lumens 2200k at 4.5 watts each. If you are wanting a brighter light on occasion you might want to install a led spot light. But that's getting into some wiring.
