Pool Equipment
The cheapest upgrade that changes when you use the pool
Everything else in this hub makes the pool work better. This one makes it exist after 8pm, which on a seasonal pool is a meaningful amount of extra swimming.
Heads up: we earn a commission if you buy through the links on this page, at no extra cost to you. It never decides the ranking — here is how we pick and here is the full disclosure. Prices are checked automatically; last verified October 8, 2026.

The light itself
Magnetic mounting, IP68 sealing, and a remote or timer. Rechargeable keeps mains power away from the water entirely, which is the version we would buy.

What it pairs with
A timer keeps the light and the pump on a schedule rather than on your memory, which matters more once the pool is used after dark.

The short version
- Magnets need a steel wall. Soft-side and resin-wall pools need the suction-cup version, and the listings rarely make that clear.
- IP68 is the rating to look for — it is a tested figure, unlike the word “waterproof”.
- One light lights a section, not a pool. Plan on two or more on anything over 12 feet.
- Rechargeable keeps mains power out of the water, which is the safest version of this product by a wide margin.
Why this is a genuinely good purchase
Most equipment on this site improves how a pool runs. This one changes how much it gets used, and that is the denominator in every cost calculation we publish — our cost per swim guide is entirely about it.
A seasonal pool is a daytime object by default. In July, dark is after 9pm; by early September it is before 8. A light does not extend the season in weeks, it extends it in hours, every evening, for nothing.
The specifications that matter
| Spec | What to look for | Why |
|---|---|---|
| Mounting | Internal magnets, or suction cups | Magnets need a steel wall to grip |
| Sealing | IP68 | A tested rating; 'waterproof' on its own is not |
| Power | Rechargeable, or 12 V with a 26 ft lead | Rechargeable keeps mains out of the pool |
| Control | Remote or app, plus a timer | A timer is what stops it running all night |
| Output | Around 10 W on mains units | Higher output covers more water |
| Colors | RGB, commonly 16 presets | Cosmetic; the mounting matters more |
The mounting question is the one that produces returns. Magnetic lights hold by clamping through the wall — a magnet inside, a magnet outside — and that only works on a steel-wall pool. An Intex or Bestway frame pool has a vinyl wall and no steel to grip, so it needs the suction-cup variant. Check which pool you have in our pool types guide before ordering.
How many you need
More than the listing photograph implies. A single unit produces a bright pool of light near itself and leaves the far side of the pool dark, which looks good in a photograph and is not the same as lighting the pool.
A workable rule from the geometry: one unit on a 10-to-12-foot pool, two on a 15-foot pool placed opposite each other, three on an 18-foot pool. That is more expensive than the headline price and it is the difference between a lit pool and a pool with a light in it.
What running one actually costs

- 10 W on a typical mains unit
- Use
- 4 hours a night
- Season
- 120 days
- US residential average rate, June 2026 [EIA]
- 18.34 ¢/kWh
10 × 4 × 120 ÷ 1,000 = 4.8 kWh 4.8 × $0.1834 ≈ $0.88
About 88 cents for a whole season
Two things worth thinking about before you fit them
The neighbors. A color-cycling pool at 11pm is visible from every window that overlooks your yard. A timer solves it, and it is the same courtesy argument our neighbors guide makes about pump hours.
Lighting is not supervision. A lit pool is easier to supervise and it does not supervise itself, and an attractively lit pool at night is more inviting to a child than a dark one. Whatever barrier you have needs to be doing its job after dark too — our pool fence roundup covers that side.
What we are scoring
We have not tested these and do not claim to. The scores reflect published specifications — mounting type, IP rating, power source, control and stated output — read against a vinyl-lined above-ground pool. Our methodology page explains how our scoring works.

Pick #1 · Using the pool after dark
Magnetic Underwater Pool Light
Various
A sealed RGB light that clamps to a steel pool wall with magnets. It is the one upgrade that changes when you use the pool rather than how you look after it.
Key specs
- Mounting
- Internal magnets, or suction cups on non-steel walls
- Sealing
- IP68 on the units worth buying
- Power
- Rechargeable battery, or 12 V with a 26 ft lead
- Control
- Remote or app; many add a timer and music sync
- Output
- Around 10 W on mains models
- Colors
- RGB, commonly 16 preset colors and several modes
How it scoresour reading of published specs, not a test result
- Sizing fit
- 7.5
- Running cost
- 9.8
- Maintenance
- 8.0
- Build
- 7.0
- Value
- 8.5
Overall 8.1 / 10
What works
- No drilling and no wall penetration — magnets hold against a steel-wall pool
- Rechargeable models keep mains electricity away from the water entirely
- A timer means it is not left on all night drawing power or annoying next door
- Genuinely extends usable hours on a pool that is otherwise a daytime object
What doesn't
- Magnets need a steel wall; soft-side and resin-wall pools need the suction-cup option
- Rechargeable units have a real runtime limit and the battery is not replaceable
- Mains models put a low-voltage lead into the water, which needs a GFCI-protected supply
- App control is the first thing to stop being supported on cheap units
Skip it if: Lighting the whole pool. One unit lights a section; a pool lit evenly takes two or more and the listings rarely say so.
What it costs to run: At 10 W, a mains unit run 4 hours a night for a 120-day season is 4.8 kWh — about $0.88 at the EIA US residential average of 18.34 cents per kWh. This is one of the few pool purchases whose running cost genuinely rounds to nothing.
One honest season: The cheapest setup that genuinely works for a season of real swimming. Nothing spare, nothing missing.

Pick #2 · Cutting the electricity bill without cutting filtration
Outdoor Pool Pump Timer
Various
A weatherproof outdoor timer is the highest-return equipment purchase on this site. Most people run the pump too long because remembering to switch it off is a chore.
#ad how this is funded · price as of October 8, 2026
Key specs
- Type
- Outdoor-rated mechanical or digital timer
- Required rating
- Must be rated for the pump's amperage and for outdoor use
- Must not defeat
- The pump's GFCI protection
How it scoresour reading of published specs, not a test result

- 8.5
- Running cost
- 9.8
- Maintenance
- 9.0
- Build
- 7.5
- Value
- 9.5
Overall 9.0 / 10
What works
- Turns your filtration from a guess into a schedule
- Pays for itself within a single season on most pools
- Lets you shift running hours to off-peak if your utility has time-of-use rates
What doesn't
- Must be genuinely outdoor-rated and correctly amperage-matched, which cheap indoor timers are not
- Never bypass or defeat the pump's GFCI to fit one
- Mechanical timers drift and need resetting after a power cut
Skip it if: Fixing an undersized pump. Running the wrong pump on a schedule just makes the schedule longer.
What it costs to run: The arithmetic that justifies it: at the EIA's June 2026 US residential average of 18.34 cents per kWh, trimming a 400 W pump from 12 hours to 8 hours a day across a 120-day season saves 192 kWh, or about $35. That is more than the timer costs.
Several seasons: Buy-once. Built and warranted to come back out of the box for a few years, if you store it properly.

Pick #3 · Music that survives being knocked in
Floating Waterproof Bluetooth Speaker
Various
A sealed speaker that floats face-up instead of sinking. The rating on the box is the only specification that separates one that lasts a season from one that lasts an afternoon.
Key specs
- Rating to look for
- IP67 or IPX7 minimum
- Floats
- Only some models — check, it is not implied by IP67
- Battery
- 14 hours typical; larger units quote up to 28
- Pairing
- Stereo pairing with a second unit on most
- Output
- From a few watts up to 80 W on the large models
- Extras
- Some add a USB-A power bank output
How it scoresour reading of published specs, not a test result
- Waterproofing
- 9.0
- Battery
- 8.5
- Sound
- 7.5
- Durability
- 8.0
- Value
- 8.0
Overall 8.2 / 10
What works
- IP67 and IPX7 are tested ratings rather than marketing words, so they mean something
- Floating face-up means a knock into the pool is an inconvenience, not a loss
- A season of poolside use is well inside a 14-hour battery
- Doubles as the speaker for everything else outdoors
What doesn't
- Waterproof and floating are two different claims and plenty of IP67 speakers sink
- Sunscreen and chlorine film build up on the grille and are awkward to clean off
- Rinse it after pool use or the seals collect salt and chemical residue
- Volume outdoors is the spec most people underestimate, and small units disappear in open air
Skip it if: Being submerged for long. An IP-rated speaker survives a dunk to a stated depth for a stated time — it is not designed to be pushed under and held there.
What it costs to run: No pool running cost at all. Consider it a yard purchase that happens to live at the pool, because that is how it gets used.
Several seasons: Buy-once. Built and warranted to come back out of the box for a few years, if you store it properly.
