Go ahead, panic and scream the sky is falling. This is old "news" to the lighting industry. They have been preparing for it for more than a decade. It isn't a new law, but just another phase of its implementation. Incandescents were being phased out of the EU already. Do your homework and find out the facts. It's going to affect your bulb choice for a floor lamp rather than anything darkroom related. Things like flood and spotlights already have LED substitutes, quite good ones in fact if you're willing to spend about $35 dollars per bulb for architectural quality ones, which will save money in the long run over the cheap home center variety anyway, which need to be replaced far more often, and have poor spectral characteristics with resultant eyestrain.
GE ALREADY shut down all their bulb mfg some time ago. They had both a consumer junk bulb division and a high-quality commerical division. But there are still numerous other makers, along with specialty online sources with huge bulb selections. Huge numbers of low-voltage halogen bulbs are still being made, both in high quality and cheap quality, and the price is actually trending down due to improvements in mass mfg. Those are unrelated to ordinary tungsten bulb mfg anyway. And LED substitutes for those are still in their adolescence and have serious color issues. But check to see if your enlarger, if old, needs something arcane, and not routinely available anymore. All of my own colorheads use readily available bulbs.
It's always smart to keep spare bulbs on hand of any variety you need.
But now that a stampede has begun, maybe after another fifty or so posts people will move on to the next hot topic, like aliens beaming up our favorite films, and taking those away.
