Seeking Assistance for LED Fixture Delay

I'm seeking some assistance regarding LED Wraparound shop lights, namely Sunco. I purchased four and they are compatible as being daisy chained (linked together).

* There is a power up delay of about one second. Is this facet normal and do all LED shop lights exhibit the same delay? I've read about the drivers and capacitors adjoined to the units but the details are unclear to me. If any could provide input here, it truly would be appreciated. All replies are welcome.

Normal. The driver takes a sec to power up. Almost all LED fixtures are like this.

Some amount of delay is unavoidable as the switch mode power supplies that power the LEDs get started. The slowest fixtures in my house are mostly shop lights. I would guess the slowest take about 3.5 second the fastest are almost instant.

Funny how 3 seconds can feel like forever sometimes.

* Thank you very much for your input. As to what I've read:"With a qualitative construction of this circuit there is no visible switch-on delay." I tried to post a link but apparently I need at least five posts.

Most all led fixtures have some sort of delay is what I have found out. Now that been said. If you have a multi meter just so you know see what the voltage is at the switch the moment you turn them on. I have had the leds take longer to turn on when the voltage is 110 volts or less at startup. This is a real issue with the “China” imported brands. Also I have had issues when a motor load like a drill, or vacuum is on the same circuit causing a “flickering” effect while operating.

* Thanks very much. I really do not know any running off 110 volts. As far as I know, 120 volts is the benchmark. However, the synopsis you present makes sense. In terms of the flickering you make mention, as running other loads on the same circuit has not ever been an issue.

* The driver is the key culprit as one of the members mentioned earlier. Not really a big deal. The lights are guaranteed for seven (7) years at 50,000 hours. If they last, the quirk (Delay) is irrelevant. Everything is made in China, so there is nothing new. I looked at all the led shop lights and decided upon the Sunco over Antlux. Sunco provided 5000k whereas the Antlux provides only 4000k in their line of shop lights. I prefer the 5000k in the garage over 4000k. Either or would suffice but again, prefer the 5000k.

Just be glad you are not using fluorescent lights! Remember the delay they had/have? Instead of just a second for the LED lights to get to full brightness you have to wait for several minutes with the fluorescents depending on how cold it is!!

Had, for practical purposes. The fluorescents I have are pretty much instant-on, even in the cold. Might be a bit dim for the first 20 seconds or so, but nothing terrible.

But yeah, old T12s with old ballasts... hummm, blink, blink, blink...

I JUST installed (20) T8 4' long LED conversion fixtures in my 30x40 garage. They take about a second to come on. Glad to read that is fairly common.

That is what I had in my basement and garage for years! You nailed it, right down to the humming and blinking!!

My pet peeve was always the one fixture that kept going blink, blink, blink until I would flip the light switch On/Off really quick 3 times. That always seemed to stop the blink, blink, blink....
