New DOE Pool Lighting Rules: What Arlington Pool Owners Need to Know

If you've tried to buy an incandescent pool light bulb lately, you probably noticed they're getting hard to find. There's a reason for that — and it's not just that LED is better.

The U.S. Department of Energy (DOE) has phased out inefficient light bulbs, and pool lights are caught up in the same rules. Here's what happened, what it means for your pool, and why this is actually good news for most pool owners.

The 45 Lumens Per Watt Rule

The DOE's energy conservation standards for General Service Lamps (GSLs) require all lamps emitting between 310 and 3,300 lumens to produce at least 45 lumens per watt. This is the same rule that killed off the old incandescent household light bulbs.

The enforcement timeline was:

• January 1, 2023 — Manufacturers stopped producing non-compliant lamps
• March 1, 2023 — Retailers prohibited from selling non-compliant stock
• August 1, 2023 — Full penalties for violations

Incandescent bulbs typically produce around 10-17 lumens per watt. That's less than half the requirement. They simply can't meet the standard.

Does This Apply to Pool Lights?

It depends on the type of light:

• Screw-in pool light bulbs (standard Edison base) — Yes, covered. These are GSLs and must meet 45 lm/W.
• Pin-base pool light bulbs — Yes, covered. Same rules apply.
• Nicheless LED pool lights (complete fixture, no replaceable bulb) — Exempt. The rule targets replaceable lamps, not full fixtures.
• Niche-mounted full fixture lights — Exempt. Same reasoning.

What This Means for Pool Owners

If You Have an Old Incandescent Pool Light

You can keep using it until it burns out. The rule doesn't require you to replace a working light. But when it dies, the replacement will be LED — and that's actually a win.

LED Pool Light Benefits

Compared to old incandescent pool bulbs, LED replacements offer:

• 80-90% less energy use — An old 300W incandescent pool light running 8 hours a night costs about $10-12/month. An equivalent LED uses 30-50W and costs about $1-2/month.
• 10x longer life — Incandescent bulbs last 1,000-2,000 hours. LED pool lights last 30,000-50,000 hours. That's years instead of months.
• Color options — Many LED pool lights offer white, color-changing, or programmable modes. Incandescent was just one color: warm yellow.
• Brighter light — LED pool lights produce more usable light per watt, so your pool actually looks better at night.

What About Replacement Cost?

An LED replacement bulb for a standard pool light fixture costs $30-80, compared to $10-20 for the old incandescent. But the LED pays for itself in energy savings within a year, and you won't be replacing it again for years.

What About Full Fixture Replacement?

If your pool has an old niche light with a burned-out socket or corroded housing, you might need to replace the whole fixture. Modern LED niche lights run $200-600 installed, but they're sealed units with 30,000+ hour lifespans and no bulbs to replace.

For nicheless lights (common in vinyl liner and fiberglass pools), LED replacements are typically $150-400 and are a direct swap.

Latest Update (July 2026)

The Trump administration recently proposed a Process Rule rewrite that would make it harder for future DOE actions to tighten efficiency standards further. They specifically named light bulbs as a product they want consumers "free to choose."

What this means: the current 45 lm/W floor is likely here to stay, but it probably won't get stricter anytime soon. Existing LED pool lights already meet the standard comfortably, so this doesn't change anything for pool owners.

Our Recommendation

If your pool light works fine, leave it. When it dies, replace with LED.

If you're still running incandescent and want better light, upgrade now. The energy savings alone will pay for the LED bulb in under a year, and you'll enjoy brighter, better-looking pool lighting every night.

If your fixture is old and corroded, replace the whole thing. A new LED niche light is a one-time investment that will last a decade or more.
