This is the NICREW SkyLED Plus in the 48 to 60 inch size, an adjustable-spectrum RGB light with a proper inline controller for ramp-up and a programmable schedule. The tunable spectrum lets red plants colour up, and it grows medium-light plants across a large tank. This listing is the large size, so match it to your tank.
- Larger tanks needing a 48 to 60 inch fixture
- Keepers who want tunable RGB spectrum and a programmable schedule
- Planted tanks where red plants should colour up
- Small tanks that need a shorter fixture, so match the size
- Anyone wanting phone-app control, since the controller is a box
- Open-top tanks where splash matters, since it is not water resistant
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.
- Adjustable RGB plus white with an inline programmable controller
- Smooth ramp-up and a schedule
- 48 to 60 inch coverage; 45W; dimmable
- The RGB channels let you tune colour and help red plants show
- Control is a separate inline box, not an app; not water resistant
- Well rated for the RGB control and even coverage on big tanks
- The RGB upgrade for larger tanks: tunable colour and a real controller, just confirm the 48 to 60 inch size fits your tank
Moderate upfront cost with low running cost at 45W and no bulbs to replace. The inline controller handles scheduling and ramping. Match the fixture length to your tank before buying.
- Buying the wrong length; this is the 48 to 60 inch size
- Not water resistant
- Algae if run too bright on a low-tech tank
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.
The adjustable RGB channels can push colour toward red, which helps red plants show, provided they also get the light, CO2 and nutrients they need.
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.
