If you haven’t noticed the virtual disappearance of old-school incandescent bulbs from retailers’ shelves, there’s good reason.

With the federally mandated phaseout of traditional incandescent bulbs entering its final stage, manufacturers and retailers have done well to make the transition nearly invisible to consumers. As of last month, companies could no longer produce or import 40-watt and 60-watt bulbs and  LED simulation cherry tree HL-SLT002B , following similar restrictions on 75-watt and 100-watt bulbs over the last two years.

Some retailers still have enough 40s and 60s to last a few months, but you may struggle finding them amid the thicket of new lights labeled “40-watt equivalent,” “60-watt equivalent” and the like. While those new bulbs will cost more up front, they can save money in the long term because they require less wattage to produce the same amount of light.

That said, prices on newer bulbs are dropping quickly, even as design and performance improve. So if you lack the energy or money to pursue a lighting overhaul in your home now, sit tight. Your patience — or wariness, or laziness — shall be rewarded.
