Product Description

Product Description

Transform an existing post-light fixture into a motion-sensing security light with this easy-to-install SL-4100-BK-A adapter from Heath/Zenith. The sensor mounts to an existing 3-inch lamp post; simply connect the wires and re-attach the top light fixture, and it's ready to go. The post-light adapter blends in nicely with the original fixture and can detect motion in a 150-degree arc. Even more, the unit's photocell sensor keeps the light off during daylight hours, while its DualBrite two-level lighting technology offers additional energy-efficient operation. Beginning at dusk, the DualBrite feature turns the light on at half power, providing soft accent lighting, which can be pre-selected to stay on for three hours, six hours, or until dawn. The light will automatically switch over to full bright security-light mode if motion is detected, remaining in full-power mode for a pre-determined amount of time (1, 5, or 10 minutes) before automatically returning to half-power accent mode. The motion-sensing post-light adapter measures 3-1/2 inches in diameter by 4-2/3 inches high and carries a 10-year limited warranty.

With over 16 unique finishes and more than 65 models, Heath/Zenith offers a vast assortment of motion-activated decorative lighting to choose from. The company supplies indoor and outdoor products ranging from door chimes and motion-sensor security lights to decorative outdoor light fixtures and wireless lighting controls. Heath/Zenith products install easily, strive to complement any decor--whether traditional or contemporary--and feature sounds, styles, and finishes that elegantly reflect the distinct personality of your home.

In DualBrite mode, you can choose 3 hours, 6 hours, or dusk to dawn. When constant light is needed, this motion-activated light has a manual override mode that allows it to function as switch-controlled light for constant on, dusk-to-dawn lighting. The motion-sensing post-light adapter measures 3-1/2 inches in diameter by 4-2/3 inches high and carries a 10-year limited warranty.

Studies show that light is the #1 deterrent to crime, and Heath Zenith's intelligent motion lighting fixtures help give the appearance of a startled homeowner turning on the lights to investigate what's going on outside. They also provide convenient illumination when you need it most, whether you're working outside at night or needing to see the steps more clearly to avoid a fall.

Needed to increase lighting in very dark front yard and sidewalk for visitors, also wanted to increase security. Saw this at Home Depot. Very easy to install in existing lamp post, just a few screws. Good directions. Simple to adjust settings although you have to unscrew and lift off post to make changes but this is easy, too. Had for 1 month so far, working perfectly.
Love 40% dim feature, provides enough light to see yard from window, increases to full brightness for 1,5 or 20 minutes when motion sensed. I set it to brighten x 5 mins when motion sensed, keep it on for 6 hours after dusk so it turns off entirely around 11 pm or midnight or later depending on season, then switches off completely unless motion sensed.

Only issue: wish it had wider degree sensor than 150 degrees, so it would sense motion over a wider area, perhaps 200 or 240 degrees.

Highly recommended.

Update added 11.11.2013. Still using the same sensor and still works great. Tried it with a LED bulb, but the dimming function didn't work (so not sure if the motion sensor did either.) I kept it in anyway, figuring it would still be less expensive to run at full power than an incandescent. But the LED bulb (from Philips) failed after just 4 months. An expensive mistake! I never did try it with a CFL. They take longer to brighten, especially if cold. I wanted instant brightening when motion is detected. So I went back to incandescent - I use clear globe bulbs - and it works great once again, excellent motion detection and lamp brightening. Increased security and better visibility for visitors is worth the higher cost of operation of the incandescent.
This can't last forever, nothing ever does, so am considering ordering another to have as backup when this eventually dies.

Purchased two of these motion detectors for multi fixture pole lights in the front yard. Lots of settings (Dusk to dawn, 1,5,20 minute turn off, 3,6 hour after dusk etc.) Easy to install (comes with the conectors), attractive and a remarkably good motion sensor... works farther than stated (90ft!).

One drawback is with the usage of florescent lights (CFL)can be problematic. It would flicker on for the first minute after startup due to the "DualBright" technology. The simple fix was to use two CFL and one standard incandescent. This solved the problem and it's working great!

Update 12/2012:

These motion sensors are working like the day I installed them. Perfect. They have not lost range or sensitivity. This is a great motion sensor!

I was tired of constantly forgetting to turn on our driveway post light. This is great! I just flip on the switch (and actually got a switch attachment to keep mt from turning it off), and the light turns on at dusk and off at dawn. In between, it dims the bulb after 5 minutes (there are other setting, I just chose 5 min.) until something else activates it.

Although this product was intended to sit on a post below a light fixture and control it, I'm using it on a short post on my entry porch to control a rope light mounted below the edge of a step that people often failed to notice. Now, when they walk up to the step, or come out the front door, the motion sensor detects their presence and turns on the rope light and makes the edge of the step impossible to miss. I appreciate the fact that the sensor only turns on the light at night and not during the day. It's been a great solution to a safety problem. For a nonstandard use like mine, it would be nice if they would offer an option of a closed cover to mount on top of the sensor to keep the weather out. Finding something to serve that purpose was a challenge. Never the less, the Motion Sensing Post Light Sensor is a well made, versatile, product.

I had been looking for an item like this for a while. I found light sensors but this is the ONLY item I found that had a light sensor, motion detector in one that i could easily add to the post lights already installed at my house.

The 1/2 power setting is an added plus. I wanted bright lights but when you have 5 lights around the front yard and they all have to be on at one time I was afraid a plane might try to land. So now the lights are not super bright until necessary. The time for the 1/2 power setting is variable for all night 3 or 6 hours I felt the 3 hr setting was perfect. If I'm expecting company after dark they almost always within the first 3 hours after sunset if not earlier. They go from 50% to 100% when motion is sensed. Really cool. Now I can have bright lights but only when needed and accent lights the rest of the time. Very nice.

They are not very expensive and installation was very simple. Anyone can install these in about 10 minutes. Be sure to set the switches where you want them and not just leave them as set when they arrive, mine came in test settings which will not be what you want when installed.

Overall I would highly recommend this product.

Easy install and better looking conversion unit than the previous one. Timer and sensor adjustments under post mount so needs to be lifted to make adjustments. However, this protects them from the weather.
