Major security design flaw, January 28, 2009
This review is from: Heath Zenith SL-5412-WH-B 300-Watt Motion-Sensing Twin Security Light, White (Tools & Home Improvement)
I bought this motion sensor floodlight to detect motion in the backyard when an intruder comes in. However, when I installed the product I had a hard time getting it to turn on again after the first time the floodlight was triggered. I could move all over the place, the LED light was blinking, and the floodlight would refuse to turn on again. This problem did not occur in TEST mode and it only manifested when I switched to the 1-5-10 minute interval.
I tried several other units from a retail store, and the units all exhibited the same behavior.
Then the light dawned when instead of continuing to move around to keep the floodlight turned on, I paused and waited for a bit after the floodlight was off--before I moved again. The floodlight finally turned on again!
It seems there is a 8-10 secs *delay* after the floodlight turns off--before the motion sensor signal can correctly trigger the floodlight to turn on again. This is a major security flaw--as someone can set up a moving object in front of the motion sensor during this time interval 'right after' the the floodlight turns off--and the floodlight will NEVER turn back on again.
The motion sensor did work ok with a pair of PAR38 CFL floodlights even though the spec did not mention this. The PAR38 CFL floodlights I purchased would not fit the floodlight shields as they were not of the same size as the PAR38 incandescent floodlights. Keep in mind that a CFL does not produce 100% of the brightness the first few minutes it is turned on.
If you are concerned about the security design flaw, don't buy this motion sensor floodlight from Heath. Otherwise, wait for 8-10 secs delay after the floodlight turns off--and then move around--if you want to trigger the floodlight again.

easy to install, works well, October 14, 2008
This review is from: Heath Zenith SL-5412-WH-B 300-Watt Motion-Sensing Twin Security Light, White (Tools & Home Improvement)
Took less than 15 minutes to install - easier than the reviewer who said it took him 2 hours but he was starting from scratch and needed to install an electrical box and switch. I had an existing fixture and switch so I just unscrewed a few screws and wire nuts and then connected the new unit. Worked the first time. The test procedure is simple. Once it tested, I sealed it with silicon as the instructions recommend. Appears to be ruggedly built, surprisingly so for a light fixture.
The only thing I didn't like is that the specs say it won't support CFL. (You must use incandescent or halogen.) In addition, the outside of the box said 120W max while the inside instructions say 150W max. Mismatches like this drive me nuts because, of course, most buyers are likely to buy the bulbs in the store at the same time before they ever get home and open the box. Also, the outside of the box never said anything about sealant. Fortunately, I had some at hand but I can imagine many homeowners would be very annoyed to get home and find they could not finish the install. At least the box does say "bulbs not included"!

This is a good product to go along with a home security system.It provides piece of mind in knowing that an intruder would have trouble accessing your residence.The sensitivity adjustment is great,it can be set to suit anyones need,no matter what size yard you have.
