Are these "instant on"?

Yes and no. They seem to take a minute or two to get to full brightness, but it's not terribly low at first.

Not sure what you mean by "instant on". They come on right away but are slow to strengthen into full brightness. So if you mean are they at full brightness when they come on than the answer is no. I do like these bulbs very much. Hope this helps and I use them outside as flood lights even though they are listed as inside.

Not really. They do give decent light right away, but they get to full brightness over about a minute. Where I use them, it's not a problem, but if it was over my desk it might bother me. (Interesting that I now see two people said yes. We all must have different ideas of "instant on" means.)

We use these in our kitchen and there is no delay. We turn the switch on and the light is immediately on!

Don't know for sure, mine are on, I actually cover them with electrical tape when the units are visible. Must not be working.

No, they do not turn on. That would cause an unnecessary draw on the battery and take away from the motor. Also having constant running lights would diminish the batteries life.

They are instant on. However, as with most cfl's they still take a couple minutes to really get up to full temp.

Yes they are static lights, so they just turn on ad a nice and bright, the whole time. I'd test to see how it looks on video to see if you like the way it looks.

No, no turn on or off - you just plug them in and they heat up, unplug to shut off.

Mine came on as soon as they were put up. I think might have left the solar panel only in the sun the day before and made sure everything was working before having them installed.

Some do. Packaging is often misleading and I would not chance these are dimmable. The ones I have say "instant on and dimmable". Also they tend to rate differently, some 800 lumens will be equivalent to a 60 bulb. Hope that helps.

I bought this for the food pantry and found they are nearly instant on. Love it!

Yes. If your light switch is on, they respond to motion both day and night. I had my electrician tweak them to stay on longer because they were set to turn off after 5 minutes of no motion.

Yes. They are turned on by supplying a ground to the pin so no controller is required.

Correct. They come on automatically at dark. You can shut them off with a switch on the back and keep the battery charged.

Yes, they are. You'll have to remove the plastic strip along the contacts for it to come on though. It's on the instructions.

Yes , these plug in to make the connection . And unplug when not in use. Note: they only plug in one way.

they will come on at any time. i like these - but i ended up getting the longer one that has the switch to turn them off for that particular reason. here's the one that i got that has the off switch. the one above does eat up a lot of batteries if you don't turn it off. alternatively you can turn the batteries around or put the small piece of paper in to turn them off during the day. but i just got this one so i can turn it off. was on my way out the door to work yesterday & didn't have time to look it up. link below. http://www.amazon.com/gp/product/B00AZR6SUY/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1#

yes. I installed > 70 of them inside my home as well as on front and back patios (under overhang). I am very pleased. I don't notice delay at all in turning on.
