The best aquarium LED lighting for 2026
The right light grows healthy plants and makes your fish glow — the wrong one grows algae. We compare LED units on PAR output, spectrum and controllability, and explain what you actually need for a low-tech carpet versus a high-tech, CO2-injected aquascape.
CHIHIROS · 60 cm · full-spectrum RGB · high-tech planted
Chihiros WRGB II Pro 60
The aquascaper's default: a bright, individually-tuned full-spectrum RGB fixture with app control and enough PAR to run a demanding, CO2-injected carpet on a 60 cm tank.

WEEK AQUA · 90 cm · RGB+UV full-spectrum · high-tech planted
Week Aqua P900 Pro
A high-output RGB+UV panel with app control aimed squarely at serious aquascapers: exceptional colour rendition, huge PAR and a UVA channel that makes reds and greens genuinely glow.

CHIHIROS · 45 cm · full-spectrum RGB · planted
Chihiros WRGB II 45
The non-Pro WRGB II: the same tunable red-green-blue-white LEDs and app control that made Chihiros the aquascaper's default, in a cheaper 45 cm fixture with slightly lower peak output.

FLUVAL · 36–46 in · app-controlled · planted
Fluval Plant 3.0
A polished, app-driven planted fixture with six LED bands and a proper 24-hour cycle — strong plant growth and clean colour without the fiddliness of the hardcore aquascaping brands.

FINNEX · 76 cm · full-spectrum · 24/7 automation
Finnex Planted+ 24/7 CC
A full-spectrum planted fixture with a genuinely set-and-forget 24/7 mode: dawn, daylight, dusk and moonlight ramp automatically, with a remote to customise every colour and intensity.

NICREW · 30-45 cm · full-spectrum · programmable controller
NICREW SkyLED Plus
A genuinely affordable planted light with a proper external controller: adjustable spectrum, programmable schedule and sunrise/sunset ramps — features that usually cost twice as much.

HYGGER · 18–24 in · full-spectrum · 24/7 planted
Hygger Advanced 24/7 LED
A full-spectrum planted bar with a genuine 24/7 auto cycle and DIY mode, run from a wired controller — most of the app-light features for a fraction of the price.

NICREW · 24–30 in · daylight + moonlight · low-tech planted
NICREW ClassicLED Plus
The default cheap upgrade for a low-tech planted tank: a high-CRI daylight-plus-moonlight bar with a built-in timer, for a fraction of the price of the app-controlled fixtures.

NICREW · nano · clip-on · white/blue/red
NICREW Clip-On Nano Light
A tiny, cheap clip-on with white, blue and red LEDs for nano and shrimp tanks — enough light for easy plants where a full bar fixture would be overkill.
