Question: How are the lights controlled? Is a timer or photocell included?
Document: We'll be ordering more for other parts of the yard.Update: After a couple of months two of the 30 lights have died and I'm going to try and seek replacement from the seller. I'm hoping this isn't going to be a trend. One star removed.
Great lights but the instructions were very limited and didn't include what size diameter the holes should be. The product &#34;Direct Wire 10 Piece Set Deck Garden Landscape White LED Lights Kit&#34; has a diagram for the hole size but its WRONG!! The whole size is just over 7/8&#34; and not 1 1/16&#34; as its on the diagram.
If you are not mounting this perpendicular to the ground, i.e. parallel with the ground for steps, you may find that some lights fit more snug than others. If you have a light that seems lose or falls out a bit, simply put a few layers of plumbers tape around the washer. You can also use a silicone sealant although this will make them slightly more difficult to pull out if you ever need to replace any. In all, very happy with these. They've been operational for about 2 months, and we've had severe weather.
These are great little lights. I've had family, friends, and a few contractors ask me where I got them--they're fairly unique. I have 30 of these installed in a pathway of concrete pavers outlining our natural grass. Installation could not be easier: Drill a hole, insert the light, connect the wires(foolproof connectors) to the next light, plug the whole chain into an outlet. The description made it sound like they were more for wood decks, but no problems so far directly buried in the ground.
These are great little accent lights, very low power. I ended up ordering 20 and was able to connect all 20 to one power supply. Holy size in diagram is wrong however, it states a 1 1/4&#34; hole size, correct size is 7/8&#34;. These lights are not bright, i.e. don't expect them to light your deck up enough to read or anything, but enough to get unobtrusive accent lighting and be able to see the floor/surrounding area at night.
The connectors appear to be water-tight and seal well when connected. The rest of the light is completely sealed and appears to be very durable. The one thing I'm not sure of yet is how well the flush mount chrome ring will hold up. It appears to be susceptible to water spots and discoloration(via oxidation?). We've only had them installed for a few days, but are so far very happy...and for the price nothing else I could find even comes close in terms of construction and appeal.
So far, no fogging/condensation under the lens.
Answer: yes
