I've been running the nicrew gen 2 on my planted tank for a few months now, and it's honestly been a surprising experience for the price. Usually, when you go for budget lighting, you expect to compromise on either the spectrum or the build quality, but this updated version seems to bridge that gap better than its predecessor. If you're like me and you enjoy having a lush, green tank without spending the same amount of money you'd spend on a used car, finding a reliable light that doesn't flicker or die after three months is a big win.
The hobby has changed a lot lately, and brands that used to be considered "entry-level" are starting to put out gear that rivals the big names. Nicrew has always been that reliable "Amazon brand," but with the Gen 2 series, they've clearly listened to some of the feedback from the community. It's not just a slight tweak; it feels like a more mature piece of equipment.
What's Actually Different This Time?
When the first generation of these lights came out, they were functional but a bit basic. They were bright, sure, but the color rendition could be a little washed out, and you usually had to buy a separate timer if you wanted anything more complex than a manual on-off switch. With the nicrew gen 2, the first thing you notice is the integrated control system. It's built right into the cord, which saves you from that messy "cable spaghetti" situation we all deal with behind our stands.
The build quality also feels a bit more robust. It's still a slim, aluminum profile—which I love because it doesn't look like a giant brick sitting on top of the glass—but it feels sturdier. The legs are adjustable, and they actually stay in place. I've had lights in the past where the wire legs would slide around if you even breathed on them, but these have a bit more tension, which is a relief when you're doing maintenance and don't want the fixture taking a swim.
Lighting Quality and Plant Growth
At the end of the day, a light is only as good as what it does for your plants. I tested the nicrew gen 2 on a standard 29-gallon tank with a mix of low and medium-light plants. I've got some Anubias, Java Fern, and a decent amount of Jungle Val. In the past, I struggled with the Val melting or just looking "meh," but after switching to this light, I noticed some significant runners within the first three weeks.
The spectrum feels much "fuller" than the original version. It uses a mix of 6500K white LEDs along with some blue and red diodes. That red is crucial—not just for the plants, but for how your fish look. If you have any red-colored fish like Cherry Barbs or even just some colorful Bettas, a pure white light can make them look a bit pale. The Gen 2 brings out those warm tones much better. It doesn't have that weird "disco ball" effect where you see individual dots of color on the substrate, either. The light blends well before it hits the water.
Par Levels and Penetration
I don't have a professional PAR meter (who does, really, unless you're a total tech geek?), but I can tell you by eye that the penetration is impressive. Even at the bottom of an 18-inch deep tank, the light reaches the foreground plants without much trouble. If you're trying to grow a high-tech carpet of HC Cuba or Monte Carlo, you might still want to look at a high-end flagship light, but for 90% of hobbyists, the nicrew gen 2 provides more than enough "oomph" to get the job done.
The Built-In Controller Experience
Let's talk about the controller because that's where most people either love or hate these units. It features a 24/7 cycle, which is a big selling point. It mimics a natural day, starting with a warm sunrise, hitting full brightness at noon, and then slowly fading into a dim blue moonlight before turning off.
One thing I really appreciate is that the transitions are smooth. Some cheap lights "step" their brightness, so you'll be sitting on the couch and suddenly the room gets 20% brighter in a split second. The nicrew gen 2 handles the ramping up and down much more gracefully.
However, it's not perfectly customizable. You're somewhat locked into their preset timings. If you're a control freak who wants to set the exact intensity of the red LEDs at 2:15 PM, this isn't the light for you. But if you just want to set it once and never touch it again, it's fantastic. It also has a memory function, so if your power goes out (which happens way too often where I live), it remembers its settings once the juice comes back on. That alone is worth the upgrade from the older models.
Heat Management and Longevity
Heat is the silent killer of LEDs. If a light gets too hot, the diodes start to dim over time, and eventually, the whole thing kicks the bucket. The nicrew gen 2 has a pretty decent heat sink design. The aluminum shell does a good job of wicking heat away from the chips.
Even after being on full blast for eight hours, the top of the fixture is warm to the touch but not "ouch, I burned my hand" hot. This is a good sign for the long-term health of the light. I've been running mine for about six months now, and I haven't noticed any dead LEDs or yellowing of the protective plastic cover.
Is It Worth the Switch?
If you're currently using the stock light that came with your aquarium kit, or maybe an old T8 fluorescent bulb, the jump to the nicrew gen 2 will feel like moving from a candle to a searchlight. The clarity it brings to the water is night and day.
For those who already own the original Nicrew ClassicLED, is it worth upgrading? I'd say yes, mainly for the built-in timer and the improved color spectrum. Being able to get rid of those bulky plug-in timers is a huge quality-of-life improvement. Plus, the light just looks better. It makes the green of the plants pop in a way the older, cooler-toned LEDs couldn't quite manage.
A Few Minor Gripes
To be fair, it's not all sunshine and rainbows. The "moonlight" mode on the 24/7 cycle is a bit bright for my taste. I prefer a very dim, subtle blue, but the nicrew gen 2 stays a bit more illuminated than I'd like during the late-night hours. I usually end up just letting it go to complete blackness to give the fish some real rest.
Also, while the legs are adjustable, they don't give you much height. If you have a lot of floating plants like Frogbit or Salvinia, the light sits pretty close to them. Sometimes I wish I could raise it up an extra inch or two to get better spread across the surface, but that's a minor complaint considering the price point.
Final Thoughts
Overall, I'm genuinely impressed with what they've done here. The nicrew gen 2 proves that you don't need to drop $200 to have a beautiful, healthy planted tank. It's a workhorse of a light that looks sleek, grows plants effectively, and doesn't require a degree in electrical engineering to program.
If you're looking for a solid mid-range light that performs like a high-end one, this is probably the best bang-for-your-buck option on the market right now. It has its quirks, but for the average hobbyist who just wants their tank to look great when they come home from work, it's a total winner. Whether you're setting up a new scape or just looking to replace an old fixture, I'd definitely put this one on your shortlist.
