Have you looked into grow lights? It seems like they satisfy the same concerns (warmth, lux) with the benefit of lower energy consumption. I quickly lost interest in throwing a lot of money at growing cheap plants, but I still remember that plants demand a <i>lot</i> of ~5500k light, and that unlike most LED gadgets, quality grow lights come with well-defined, well-tested specs.
I came across this idea here first: Eliezer Yudkowsky’s <i>Inadequate Equilibria</i> -- great read!<p><a href="https://equilibriabook.com/" rel="nofollow">https://equilibriabook.com/</a>
