When the evening swim ends and the spa lights come on, the water takes on a different mood, and the right light makes that moment easy. This best swim spa lights roundup gives a short verdict up front: pick a battery puck if your spa is portable or you want light without wiring, and pick a wired niche light only if your spa already has a 6 inch wet niche to fit it.
The listings below were collected 4 November 2026. The roundup covers battery pucks with remotes and suction cups, plus wired niche lights for inground spas, and it leaves a figure as Not stated wherever a listing does not state it.

best swim spa lights at a glance
| Battery pucks | Wired niche lights | |
|---|---|---|
| Power | Batteries, no wiring | 12V AC or 120V AC, wired |
| Colors | 16 colors and 4 modes on the 2-packs and the GlowTub puck | 7 hues and 7 effects on the 12V light, cool white only on the 120V light |
| Control | Remote on every puck | Remote on the 12V light, no remote stated on the 120V light |

Battery pucks vs wired niche lights
The battery pucks are drop-in lights: a puck with a suction cup, a remote and batteries, with no wiring and no install beyond sticking the cup to a smooth surface. The YiaMia and Qoolife pucks come as 2-packs with 16 colors and 4 dynamic modes, while the GlowTub puck is a single light with 16 colors and 4 modes named Flash, Strobe, Fade and Smooth. Their limits are battery supply, remote range underwater and suction surface, all stated in the listings.
The wired niche lights are replacements, not drop-ins: a fixed light that fits a 6 inch wet niche in an inground spa or pool. The 12V light needs a transformer that is not included, while the 120V light needs no transformer for its install. Neither suits a portable spa with no niche, and the 120V light gives cool white only, with no color change stated.
Power, fit and install
Power splits the roundup cleanly. The YiaMia puck runs on 3 AAA batteries that are not included. The GlowTub puck runs on 3 AAA batteries that are not included. The Qoolife puck is battery powered, with no battery type stated. The SURAIELEC 12V light runs on a 12V AC system with a transformer that is not included. The SURAIELEC 120V light runs on 120V AC with no transformer needed.
Fit needs the same care. The YiaMia listing states that suction cups perform best on smooth, non-porous surfaces such as acrylic, fiberglass and tile. The GlowTub listing states that its light is not compatible with inflatable tubs or pools. The wired lights fit only 6 inch wet niches, including Pentair, Hayward and Jandy niches. For heating choices on the same spa, see our best swim spa heater roundup.
These are scored on the Chill Score, which weighs performance, build and value most, with safety where it applies, and warranty. None states a UL or ETL listing, so safety is zero for all. The YiaMia listing states a 12-month warranty, the 12V listing states a 3-year warranty, and the 120V listing states a 5-year warranty; the other listings state no warranty term, so the warranty scores differ.
| Product | Chill Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| YiaMia RGB 2-Pack | 9.5 | 29 | 20 | 21 | 0 | 2 |
| SURAIELEC 120V White | 9.4 | 22 | 21 | 18 | 0 | 4 |
| SURAIELEC 12V Color | 9.3 | 21 | 21 | 18 | 0 | 3 |
| Qoolife RGB 2-Pack | 9.3 | 27 | 20 | 21 | 0 | 0 |
| GlowTub LED Puck | 9.3 | 26 | 19 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Choose battery pucks if
- You want light without wiring, with a remote and a suction cup mount.
- You want color-changing light: 16 colors and 4 modes on the pucks here.
- You want a 2-pack to light more than one spot in the spa.
- Your spa surface is smooth, so a suction cup holds.
Choose a wired niche light if
- Your spa already has a 6 inch wet niche to fit.
- You want a fixed light with a cord, not batteries to replace.
- You want color-changing wired light: the 12V light gives 7 hues and 7 effects.
- You want cool white wired light with a 5-year warranty: the 120V light.
Check Your Space First
- Measure the niche before ordering a wired light: both wired lights fit 6 inch wet niches only.
- Check the suction surface for a puck: smooth, non-porous surfaces hold best, and the GlowTub puck does not suit inflatable tubs.
- Check the battery supply: the YiaMia and GlowTub pucks need 3 AAA batteries that are not included, and the Qoolife listing states no battery type.
- Check the transformer question: the 12V light needs a transformer that is not included, while the 120V light needs none.
- Check the temperature ceiling on the YiaMia listing: water above 80 degrees C (176 degrees F) is not allowed for that light.

Can I change colors on all of these lights?
No, four of the five change colors and one does not. The YiaMia, Qoolife and GlowTub pucks give 16 colors and 4 modes. The 12V wired light gives 7 hues and 7 effects. The 120V wired light gives cool white only, with no color change stated.
What warranty do these lights carry?

Do the remotes work underwater?
Range falls underwater on the YiaMia puck: up to 33 feet in open air, but within 5 feet of the submerged lights for reliable use. The Qoolife remote is not water resistant and must be kept away from water. The GlowTub remote is splash-resistant.
