Wondering if snow will disable the photocell at night?? Any info appreciated. Thanks!!!
By Tony from MI on September 10, 2014
Answer:I could not be happier with the unit, it has worked without any problems and I live in MI so we do get a little snow now and then, I would recommend this light to everyone.
By Jim from Maryland on September 10, 2014
Answer:My educated guess is that it depends so if you are asking about snow building-up on and over the sensor lens in the dark that could indeed "blind" the sensor. The ambient light sensor component would correctly "think" it's dark and give the motion-detect component permission to light the two LEDs if there was a qualified motion event. That's the function that would be affected by being covered up. Depending on the amount of lens build-up the less likely the motion-detect sensor could establish a thermal picture of its field of view. Stationary bodies producing heat might move but may not trip the "Lights On" threshold or, new bodies could enter the field of view with the same result. On the other hand, I doubt that you'd see false Lights On unless of course the snow cover were to fall off. That event could be seen as a drastic change in the thermal image and qualify as a one time Lights On event. I would think that if you can angle the spotlight somewhat downwards or under an overhang you might or would avoid the snow build-up. BTW, If you're unfamiliar with these Mr. Beams motion lights, this dual-LED model throws an immense but well-defined circle of light. When I mounted one to guard my driveway I didn't aim it downwards enough. Yes it flooded the double-wide driveway + the street + the front of my neighbor's house. I had to increase the down-angle which for snow is a good thing. Hope this helps.

Answer:Well we don't get much snow in Florida but, with the lamp mounted in a even slight downward angle, it would take quite a snow fall to get to the eye. If you look a the picture of the lamp the eye sits in the lowest spot on the lamp, so the top would give it good protection.
But maybe with a near sideways blowing snow you may reduce the capability.
I'll be honest, had ours for a while now and it's pretty darn effective and quick to respond to movement in an easy 180 degree+ side to side range. Like said we don't get snow, but boy do we get rain. And even in mega downpours it still pops on when the eye picks up a movement.

Answer:I don't think so, the light is pretty smart. It only sees big objects moving such as humans or animals

How many hours does it work with 4 D batteries?
By Sid from Galveston, Texas on September 29, 2014
Answer:Can't say for sure how many hours. I know they last a long time. It depends on how often the light gets turned on. Mine is activated for a short time. It's by my garage and gets turned on at night when I'm out there. Have had mine for about 6 months so far, still bright and same batteries.
By Len & Debra from Upstate NY on September 29, 2014
Answer:With normal use, this light's manufacturer says that the batteries will last more than 1 year. I'm using and happy with this light and I believe the manufacturer's claim that new batteries should last more than 1 year. You will want the 300 lumens light output that this light provides. My understanding is that the light will eventually stay lit for a long time, instead of automatically turning off, as the 1st indication that it's time to replace the 4 D batteries. Hope this info from a satisfied Pegasus customer helps you!
By S B from Baton Rouge, LA on September 29, 2014
Answer:We have had this light for a few months; it is motion activities so the batteries seem to last for a long time. We haven't had to replace them as of today.
By Lynn from Austin, TX on September 29, 2014
Answer:I have been using this light for nearly 6 months. Of course how long the batteries last is a function of how many times you use the light. As I recall the documentation indicated that 4 batteries would last several thousand cycles. The light appears to be set for about 30 seconds so it does not waste power when you are not using it. I like the light so much I bought 7 of them - makes approaching the house at night much safer.
By Paul from Homerville, GA on September 29, 2014
Answer:Mine on my barn are still working great on the original batteries after about a year. These are great security lights and quite bright.

Is changing batteries a simple operation?
By Joe W from Pensacola, FL on December 31, 2013
Answer:Changing batteries is an easy procedure depending on how you mount the light. We use ours in a large walk-in pantry where it's mounted on a wall near the ceiling. We need a step stool or small ladder to change the batteries, but that would be true for changing bulbs in most fixtures or changing batteries in a smoke detector.
By Glen from Los Angeles, CA on December 31, 2013
Answer:Yes, changing the batteries is very simple and easy. Check out this youtube video. Click
By Lynn from Austin, TX on December 31, 2013
Answer:Changing the batteries is not difficult. There is a single "wing nut" to release the light from the mounting bracket. This may involve climbing if you mounted them out of reach from the ground. Once the fixture is down a quick twist of the lens portion and release two clips that hold the batteries in place. Less than a minute. Be sure to look at it as you are taking it apart to see how the batteries are to be installed.

MAKE SURE ARROW & LOCK SYMBOLS ARE IN LINE TO EACH OTHER FOR A TIGHT SEAL. ITS THAT EASY YOUR DONE.
By Richard Davies from Naples, Florida on January 1, 2014
Answer:Changing the batteries is very simple and quick as long as you are able to safely able to reach the light fixture without having to stretch too far. If you can do that, it just takes about 10 seconds to change batteries. I have found that changing the batteries is not needed often.
By valerie from Murrysville,pa on January 1, 2014
Answer:Changing batteries is super simple. You just take off the head and there's the battery case. I've done it many times.
By Richard from Belmar, NJ on January 1, 2014
Answer:Great product. All you do is take the top off, slide the battery out and put new ones in. The batteries will last for almost a year so you won't have to do this very often.
By Steve from Tampa on January 1, 2014
Answer:It's as simple as changing batteries in a flashlight.
By Paul from Leominster, MA. on January 1, 2014
Answer:This is a great spotlight and is very bright white light -- it has worked well outside for my needs. Changing the batteries is a very simple process. Just unscrew the head of the light, install the batteries, and screw it back together lining up the markers to ensure it is sealed and water tight. Just like installing or changing batteries in a typical hand held flashlight. Good luck!
By Jim Bocchini from Miramar Bh. Fl. on January 1, 2014
Answer:Yes, very easy. And the light works great.
By Mike from Schaumburg, IL on January 1, 2014
Answer:Super simple. It takes 4 D batteries and they last a long time. I really like it. I have mine at the end of my driveway on the mailbox post. Still working even in 0 degrees temps.
By Kenneth from Scranton, PA on January 1, 2014
Answer:Very simple to change batteries and the spotlight works great.
By Shelley from Hamilton, MT on January 1, 2014
Answer:Actually it is very simple to change the batteries as the back comes off and the batteries are right there.
By Steve from Pittsburgh, PA on January 1, 2014
Answer:Very easy. Simply turn the face plate counter clockwise and the battery compartment comes out to be able to change batteries.
By SUSANNE from SCIO, NY on January 1, 2014
Answer:Yes...it's very easy....just like changing the batteries in a flashlight.
By John Conley from Trinity, FL on January 1, 2014
Answer:The batteries are exceptionally easy to replace. The face of the light, in which the 2 bulbs and sensor are located, is simply turned (there are marks that indicate which way to turn as well as indicating closed and open) to the open marker and the face slides out with the batteries. Two plastic locking rods are pushed releasing the batteries and permitting replacement (the only occasionally difficult part is sometimes one holding rod does not release completely and the process has to be repeated to get all 4 batteries released at the same time). Everything is marked to ensure correct placement of the battery when installing new ones. Simply install the 4 replacement batteries, replace it in the face with the batteries into the base and turn. The base that is installed on your house, fence, or whatever never needs to be removed. I have replaced the batteries in one unit and the whole process took me no more than 3 minutes at most. I hope this answers your question.
By Rick Sauter from Felton, PA on January 1, 2014
Answer:Yes it is quite simple to change the batteries. The level of difficulty does increase depending where you have it mounted. If it is mounted quite high or hard to reach this would require more time. The actual time to replace the batteries is less than two minutes once you have access to the light.
By Daniel from Syracuse, UT on January 1, 2014
Answer:Yes. The lens assembly just comes off with a slight twist. The battery compartment is attached to the lens assembly that detached. This makes it easy to change the batteries and then re-install the lens assembly when done.
By Tom from NJ on January 2, 2014
Answer:Yes, very similar to changing the batteries in a flashlight.
