Would LED Lunar Lights affect my planted tank?
 
Would using a couple of LED Lunar Lights at night ( something like similar to this Aquarium LED Lights: Current USA TrueLumen LED Lunar Lights ) have any affect on the plants or finish in my tank? Or is it small enough to have no impact?

Thanks for your time! =)

Though if anyone has any input, it would be appreciated =)

All I'll say is to add my vote to the keep it dark crowd. Light is light, doesn't mater if it's white or blue it will still keep you up at night.

In a dense forest, or jungle as most of these fish come from, it's pitch black at night due to the extremely dense tree cover.

Here's an addtional/side question..

Could something like that be used to ease the transition when the timer shuts the lights on and off? Maybe have a feint light on 15 mins before the main lights flick on, and 15 mins after the main lights flick off?

This way its more of a gradual darkness rather than a flash. Was reading that the fish can stress and need time to adjust when the lights just flick on and off.

Yes to the first question [creating gradual light on/light off periods]. On the second question, if this refers to a second tank light such as the "moonbeam" thing, I would extend the period to 30 minutes (or longer). Depends on ambient room light too. More here:

The overhead tank light should never come on or go off in a dark room, "dark" meaning as in no ambient light. That is highly stressful to fish.

Gotcha. When it turns on in the morning there shouldn't be an issue, I have it set for late morning, when there's always a bit of light in the room. I'm mostly concerned about when it turns off at night, I can't always guarantee I'll be there to make sure the room has lamps on.

P.S. Thanks for the article! ^,^

I solved this problem by having a room light on its own timer. My tank lights come on at 10am, and although the shades are mainly closed, the room is light; you could easily read a book in the ambient light. In the evening the lights go off at 6pm, and in summer there is still daylight of course, but during the several months of winter, darknes outside. So I have a wall light on a timer, it comes on at 5.55pm and goes off at 6.55pm. I tested this by sitting quietly in the room when the tanks lights went off, and there was no discernable shock by any of the fish in their tanks. But before I did this, I would hear fish crashing into the end walls and jumping against the cover glass in all the tanks when the tank light went out in a dark room. B.
