Single Channel LED Ramp Timer, LED Digital Dimmer for NICREW ClassicLED, ClassicLED Plus Ho, and JTL Series Clip-on Light

I had been using plug in timers on my 4 aquariums for many years. As I've replaced most of my lights with Fluval bluetooth models, which use an app to control settings, I have been able to do away with the bulky timers. Just 1 tank remained, a Superfish 80 litre, which has a built in led light that is turned on and off and dimmed by touch buttons. Rather than use the old plug in timer I looked for an electronic timer and came across the Nicrew one. I didn't want anything fancy; just something to turn the light on gradually and off again. It's a simple job to plug this into the lead of the existing light, turn it on, set the time and the on/off functions and away you go.One word of caution; make sure your light has a connector in it's lead compatible with the Nicrew connector. This would not have fitted one of my Fluval lights. Be aware that if the power to the Nicrew timer is cut you will need to reset the time when you turn it back on but it does retain any settings you have entered.Overall a very neat, inexpensive bit of kit.

I bought this to control the lighting in my Interpet Insight 64l aquarium and it does the job perfectly! Setup was simple and the timer works flawlessly with my lighting unit. I currently have the Interpet 470mm Triple Bright White LED lighting unit and this controller/timer works without any issues at all. Sunrise and sunset takes approximately 15 mins from start to finish with the Interpet 470mm Triple LED unit. (Times may vary on bigger/smaller lighting units).Setup was as easy as...Set main clock,Set "ON" time,Set "OFF" time,Select F1 - Sunrise/Sunset mode (F2 for instant on/off),Sit back and enjoy the sunrise and sunset effect at your chosen times!The timer also has a override button to turn the lighting on/off when required, after using the override button you just hit the Setting button to return to "Timer mode". Couldn't be any easier!Another added bonus with this timer is the ability to adjust the LED lighting brightness whilst the unit is on, other sunrise/sunset timers don't offer this function so is yet another advantage of this timer/dimmer unit.A fantastic bit of kit and well worth every penny!

Using this to dim a 7W aquarium light and works perfectly. Timer is easy to set, and I really like the option of being able to dim the light. Only four stars because finding the right button presses to get to the dimming settings is not intuitive, so better not lose that manual! Else very nice item, can recommend.

I have a twinstar 600S. The Nicrew dimmer worked perfectly, included adapter made sure connections fit perfectly. Easy to install, lovely 15min sunrise/sunset feature and dimmer 1-100%. Only negative is that you can't customize the sunrise/sunset at all, but the automatic 15minute setting is very good.

Brilliant bit of kit for the money, easy to install and functional, dims lights up and down as timer comes on and off, exaclty what I wanted it to do, works so well that I orders a second one, a single and dual channel one

The first thing I noticed about this was that it's much smaller than I was expecting (my own perception - I should've looked at the dimensions!)The second thing was that it feels a bit plasticky.However, it works and so far it works very well.It was easy to set the time and programme following the instructions.You cannot set the duration of the sunrise/sunset - it's a 15 minute fixed cycle but that seems to be perfectly fine from what I can see.Although I didn't need the adaptors for a different size cable, it's nice that they're included in the price.No complaints at all so far.

The first one I received, the ‘-/min‘ button didn’t work properly, it wouldn’t register a short press but would a long press and therefore i could not adjust the brightness and setting the minute time was a nightmare.The 2nd one I received all worked but when the light was dimmed at any level, the unit started to make a loud buzz, you can hear it and definitely will annoy you. The unit comes with an adapter for 2.5mm as standard it’s 2.1mm, however 2nd unit was missing this!If it worked as it should then this unit is ok, it allows you to set sunrise and sunset which ramps up the light from off to your set brightness in a period of 15mins which is non configurable. You can only set the on time and the off time and whether to have sunrise/sunset or just straight on/off.So with two units both suffering defects, I bought another unit similar to this but works perfectly, giving you 8 times that you can configure the brightness to simulate sunset/sunrise. It’s a bit more complicated to configure but works perfectly unlike this one.Maybe I’m just super unlucky but 2 faulty units does not say much about the manufacturers quality control and the robustness of this unit.

Easy to set up, and seems to work well. However it makes a high-pitched whining noise the entire time it’s dimming the light for sunset/sunrise. Not sure if this is avoidable, but it’s pretty loud. Might not be a worry if your tank is not in your front room.
