And, as a German:
EC 244/2009 led to lots of LED manufacturers trying to push their products and competing, leading to 8W 1200 Lumen warm-white LED light bulbs being available for less than 15€ by now everywhere.
In my family, before the regulation we had several light bulbs and mercury-bulbs from IKEA which were expensive, but now we switched to these LEDs and have better light at lower cost. (At $0.40 per kWh German electricity prices make switching to LED make sense).
Also many fun fair attraction owners switched to LED, and quickly discovered how having a programmable LED array is far better for flashy lights than few larger lights.

In general, though: Yes. It always happens.
Same as in the refugee crisis, too. For the cost of building fences between all the EU countries that we did, we could have built a fence at the outer borders twice.
