Way2top LED Dimmer Question

I have a Twinstar 600SA light. It can go quite bright and is height adjustable. Nice light but does not even come with an on/off switch, much less a timer/dimmer.

Based upon a YouTube review by Jurijs Jutjajevs I purchased a Way2top LED dimmer which has 8 adjustment points for brightness/time.

I wonder if anyone here has the same dimmer and might "shed some light" on setting it up. The included instructions are worthless. Jurijs gives some good tips but I do not seem to be able to turn off completely when I set a time with brightness of 0. Well past the last programmed setting it is still running in a very low moonlight level.

Worst case I could always use an Alexa powerplug to turn it on and off while maintaining the ramp-up features but this seems to defeat one of it's features.

Any users here?

Not a user though have used "like models" a bit.
quick review seems to show different types of instability are , if not common, enough to be noticed..

Since it's nothing but a MOSFET switch circuit run by 5V logic..it should quench to zero.. All mine did.
That said it doesn't really take much to light Led's, little bit of leakage voltage.

Sounds like a bad copy...OR you have night mode on yet not seeing a way to shut it off..

Second problem is it looks like if you power off the unit it will resume where it left off not the "current time".

I’ve got mingdak and Nicrew Pro dimmers which are basically same class as those, Nicrew looks just like it. And yes at lowest ends of ramps you’ll see them jumping until they reach about 20% intensity. But that’s what you get for $20 or less. I don’t worry about it.

You could easily use one of these analog dimmers and a standard mains timer if it sets your OCD off to much. Even though their flawed I have no problem with their function to price ratio.

The one problem that set me off was sometimes, completely at random, if I had 1st or last step set at 20% or less the light would go into strobing. No reason why, happened on completely random days it would do that I could find. Basically I set my 1st/last steps at 25% or higher and it’s completely went away. It couldn’t have been good for light and/or maybe even timer itself to start doing that. You could even hear pulse through light as a rapid high frequency whine. Maybe @jeffkrol has a explanation of why, sometimes, it would randomly start doing that.

Rats. That would rule out using an Alexa powerplug...

I read through the long list of comments from Jurijs Jutjajevs's video and it turned out that he has modified his original schedule due to flickering at low brightness settings and the "moonlight" issue.

Here is his recommendation. I am trying it today. The 0% setting gets rid of the moonlight and the fast switch up to 10% skips past the tendancy to flicker. I have not seen flickering but that may be dependent upon the light itself. Someone else suggested not using all of the 8 steps.

If I can get it working for $20 I will be very happy, otherwise I will keep searching. It is a bit odd that TwinStar does not have dimming and programming built in considering the price...

Dimmer schedule:
1: 0%
One minute between
2: 10%
Ramp up over 30 mins
3: 100%
Keep 7,5hours for the main day cycle
4: 100%
Ramp down over 30 mins
5: 10%
One minute between
6: 0%

On the mingdak and Nicrew Pro the last event you set time for is OFF, there is no power/intensity setting. No problem with having it go completely off.

My steps are 25%-45%-65%-45%-25%-OFF

You can get around them having no battery backup for clock memory by putting a mains timer in front of its power supply then you just use it for timing the steps/ramps. Every time mains power is cut clock will reset to zero (midnight), when power comes back on it will start going through steps again.

Example of settings youíll put in....
00:[email protected]%
01:[email protected]%
04:[email protected]%
08:[email protected]%
11:[email protected]%
12:[email protected]

Thatís a 12hr light cycle it just stepped through. Your mains timer, which has a battery back up, you set for 12hr+min.

Why they couldnít add a button cell battery for clock memory to these units i have no idea, it couldnít raise the price more than say a couple dollars a unit at most. Again we get what we pay for.

I just bought the same dimmer and a Twinstar 900s.

My original programming only used 7 of the 8 intervals with the last one programmed for zero power. It didn't work, the light never turned off.

I then programmed all 8 intervals with #s 1 and 8 programmed at zero, and set minimums at 15%.
This works. So far I'm very pleased with both the light and the timer.

I purchased the Way2Top dimmer for the Twinstar 600SP after watching Jurijs video.

I'm still tweaking the ramp time with my co2. I set #7 to 1% for ambient lighting then #8 to 0 and it shuts down. But soon after, my TP-link cuts power entirely. I start at 1% in the morning not zero. ...2 weeks and no issues.

Mine is working well now also with the new schedule. Interesting that you are able to cut power and that it still works the next day when power resumes. I assume that this is because when you resume power it resumes at #1 again. I guess this also means that it does keep the actual time for a while after power is cut.

I just assume that, for this type of device nowadays, it will have a built-in battery for memory. and it won't matter what level I start with. if you recall on Jurijs' video, at 8m 50s, he said 'I used to have ten percent there before...' so it does have memory.

They have memory for all your steps/intensity (nonvolatile memory) but they have no battery backup for actual clock time. Power goes out it, resets to 00:00 (midnight). I keep hoping that some makers in this price/class would implement that feature but so far have been disappointed. Where I live have had a slew of quick brown/blackouts last two years, not a bunch of big storms, just quick flashes usually during day but enough to mess these timers clock up.

But Iíve got 2 of these on tubs downstairs connected to a reg dig timer that does have battery back up. When power outages happen and then comes back on they will be out of sync for rest of that day, but next days on/off power cycle happens and their both back in sync with mains timer. Since I started using them this way the fact they have no clock time backup is irrelevant, 1min after power comes back on they start running through cycle on all tanks. Next day with no power outage events their back up in perfect sync.

Let us know if yours behave differently (has a actual clock backup).

I think mine behaves differently. Power is cut off for 7 hours. When it's back on, clock-time still matches my mobile phone.
