If it is a surge protector, then it often has two lights. This optional second light reports a defective safety ground. Always required first light reports protector circuits have disconnected to avert a house fire. Some glow when OK. Others glow when a failure has occurred. Consult the manufacturer's instructions.

A power strip typically has only one light to indicate power.

Both protector and non-protector strips, if minimally safe, feature a circuit breaker that disconnects all lights and receptacles.

What is minimum recommended surge protection for an iMac?

First of all look for a surge protector with a UL (Underwriters Laboratory) rating. If it does not have one you can rest assured is junk. But just because it has one does not mean is an excellent surge protector. Be sure that the product is listed as a transient voltage surge suppressor. Get a surge protector with a minimum of 1200 joules. Normally the more money you spend the better protection you get but, that is not necessarily always the case.

Why is it important to have an indicate light on a surge suppressor for your computer?

Answer Most of the surge suppressor indicator lights only show if the power is present and turned on. It does not add any other functionality in terms of surge suppression. Only if a particular model indicator shows that there was a surge on power line, it makes it more useful for the user as person can investigate reason or surge if it is happening repeatedly. Iindicator should be clearable manually by user. - Neeraj Sharma "...it's important a surge supressor has a light indicator that says the supressor part of the device is still working. Otherwise, you might not have protection" A+ Guide to Managing & Maintaining your PC (page 161) -MonkGizmo That indicator light cannot report all failures. Normal failure mode for a protector is to degrade. That light cannot report a degraded protector. That light only reports that a surge, much too large for the protector, caused its thermal fuse to disconnect protector parts as fast as possible. To avert a fire. That light can only report a type of failure that says a protector was grossly undersized. And a potential threat to human life if that fuse did not blow fast enough.

Will a surge protector last longer if it's unplugged from the wall outlet during an electrical storm?

Possibly, but that's kind of missing the whole point of a surge protector. The surge protector exists to protect the things that are plugged into it. If you're not using those devices anyway during the storm, sure, go ahead and unplug the surge protector... but you could also have just unplugged the devices themselves from the wall and not bought a surge protector in the first place. Also, storms don't directly damage surge protectors. Stopping surges damages surge protectors. If there's no surge, it doesn't matter if the surge protector is plugged in or not.
