Finnex Stingray 3 (24 in)
A slim, controllable low-profile light with a 24/7 Lunar+ cycle and extendable legs. Understated output — good for low-to-medium light tanks and a clean look, less so for demanding carpets.
- +Slim profile, low-glare fixture with even coverage — a clean, modern look over the tank
- +Controllable 24/7 Lunar+ cycle that ramps up to moonlight on a programmable schedule
- +Full spectrum and bright enough for low and medium light plants
- +Extendable, adjustable legs fit the tank rim
- −Newer listing with few reviews so far
- −Modest output — not a high-light fixture for demanding carpet plants
This is the Finnex Stingray 3 in the 24 inch size, a slim, low-profile controllable light with a 24/7 Lunar+ cycle and extendable legs. Its output is understated, which suits low-to-medium light tanks and a clean look, but not demanding carpets.
- Low-to-medium light planted tanks
- Keepers who want a slim, low-glare, modern-looking fixture
- Anyone who wants a controllable 24/7 cycle with moonlight
- High-light carpet plants, which need more output
- Buyers who want a long review history, since this listing is newer
- Very deep tanks, given its modest PAR at depth
We separate what the maker claims from what independent sources confirm, what owners report, and where we are drawing an inference. We do not bench-test products.
- Slim, low-glare full-spectrum fixture
- Controllable 24/7 Lunar+ cycle with ramp-up
- Extendable legs; splash-resistant
- Output is modest, suited to low and medium light
- This is the 24 inch size
- Well regarded for the clean look; a newer listing with few reviews so far
- A tasteful low-profile light for low-to-medium tanks; choose it for the look and control, not for high-light growth
Moderate upfront cost, low running cost, no bulbs to replace. The 24/7 controller handles scheduling. Its modest output means algae is easier to avoid but demanding plants are out of reach.
- Modest output, so demanding carpets will not thrive
- Wrong length if not matched to the tank
- Few reviews so far, so long-term reliability is less proven
We do not measure PAR; figures are the manufacturer's specification and paraphrased owner reports. Plant results depend on CO2, nutrients and stocking, which are beyond a light's specification. We give gear and method guidance only, not livestock or disease advice; route fish-health questions to a veterinarian or an established authority.
Not a demanding high-light carpet. It suits low-to-medium light plants; for carpets with CO2, a higher-output fixture is the better choice.
It grows the plant levels stated in its spec. Too much light without matching CO2 and nutrients drives algae, so dim it if you see algae rather than adding more light.
Check the spec above; several of these fixtures are not water resistant, so mount them clear of splash and condensation.
