I've owned this light for since June or July of 2022. I've used the arm, which would do better if it didn't bend out into the room. I've used all whites, the timer, all blues, and I've even gone so far as to chain it over a sump tank with limited overhead space. Today, I realized that my ability to mix spectrum is completely gone after leaving the whites on 100% for a few months. I no longer have a third choice while using the wire attached controller. You will notice I have the product 4 stars. In the grand scheme of reef lights bang for buck, this is a 5 star reef light. However, reliability/ customisability problems experienced by myself and other users over time would cause you to understand this product isn't entirely bulletproof.My basic issues with it:1. The adapter is big so it takes up a lot of space on the power strip if you aren't creative.2. I lost the ability to mix blue and white so now I'm running it all blue. This means it has limited efficacy for me moving forward.3. It wouldn't be hard to program in more light settings into the device but the $50 controller was created as an upsale instead of pricing the light properly at $110 in the first place and shipping the unit with the controller.4. I use many knock off products and I wish companies using barrel jacks began shipping a heat shrink sleeve for them to prevent sparking or unexpected disconnections.5. The product should advertise the ability to hang in low clearance areas with a simple chain, rope, hook, etc.6. In a power surge or outage, your timer will lose the start date. This means if it's 6pm and your day on the reef light was ending, and you get a power outage, when it reboots it will start immediately back at daytime and you'll get your reef slapped with double the photoperiod you intended. I recommend the wyze plugs or a similar smart plug with a programmable timer to avoid this hangup entirely.I use this on my quarantine tank so light isn't super important to me but at the end of the day my nicrew products always develop some problem or another after a period of 1-2 years and I love the spectrum they put out for the money but if you are serious about reefing then you need to eventually pony up for more reliable products down the road. Nicrew makes great products but reef lights are treated very poorly when you think about it and being able to stand up to general use and wear is important to me. I will always have nicrew lights in my backup supply of lights (I have 3 of the 150w hyperreef and I run nicrew currently on all my tanks with great success) , but I'm currently saving up for a product with larger power supply because I have had to modify the ones that fail to accept better power supply. Nicrew if you read this I'm happy to pay $300 for hyper reef with controller and proper power supply pre wired. Your 150w hyper reef power supply currently runs at max of rated load which is very unsafe and fire hazard. Many users I have talked to also have overhearing power supply problems.Photos of my reef tanks are attached. The power supply comparison I am talking about is attached.If nicrew fix power supply problem with heat dissipation I'd be happy to rate 5 stars. I know this probably makes the light more expensive for other people but I think reliable product feature like this is important if customer has to either buy one anyway down the road to fix the problem or write off your product as bad/limited shelf life when the lights are actually an amazing product and it's mostly just a victim of corners being cut on LED driver. If nicrew fixed this problem then I wouldn't be changing to light system that has fixed this problem and I think the lights would be much better reputation than the amazing reputation the already have, I just want to make sure I give fair review and I think the pros outweigh the cons of you are willing to invest to fix the problem as a end user or if Nicrew willing to raise the price but fix the problem themselves as manufacturer.I have to go buy more LED driver, or aluminum block to dissipate heat properly from the unit to avoid burnout/ failure of unit and I recommend all nicrew used do this if you don't want to buy another one down the road. Yes it's not fun but resoldering new LED driver is easy if nicrew not willing to update product and you'll get much longer life out of the lights. They are really truly that good and I actually would guess the failure of mixing light I have is electrical overload based problem from overuse.Overall very good product and better than most on the market. Many more expensive lights, even Radion and many "best market brands" do not have proper power supply so this is more of a problem relating to building a good product for myself that will last many years instead of repurchasing or having backups all the time.Every time I have reefers over they always love the spectrum of my nicrew and my lights so I will probably end up buying 3 more 150w backups but given price of the this unit you may as well rebuy it if something goes wrong. It is that good for the money. The laser temps attached are for 150w nicrew power supply, and my modified one of Nicrew reads this review. But you can see nicrew grows coral very well and of they want to sponsor me to to talk about their other products I am happy to provide logical feedback on them. At the end of the day, many reefer think buying fancy brand is the safe thing to do but unfortunately everyone wants to make money so you as hobbyist need to not be naive and learn to read electrical output ratings of these products when they are in use and that goes for all electronics in reef tank not just nicrew products and not just lights. You are only as good as your habits.
