I finally got that Tendelux installed and mounted. I used the "strip across the soffit" method but modified that just a little. I cut two, short, extra pieces of 1-1/2" flat aluminum stock and used them to clamp the strip into position rather than silicon or a screw through the flashing lip. The location is on the soffit where it extends past the end of the house to match overhang of the gable end soffit. I was able to get the wiring in with no holes at all, pulled the end piece of soffit and grabbed the wire I had put in from the attic with no problems. I installed a CAT6 at the same time because I want a camera there sometime later this spring.
It is providing fill light at extreme range where I wanted it to, along a property line. Keep in mind the camera is about 120 feet from the light. I'll get some screen captures tomorrow, but unless you look carefully it's hard to see. I'm sure it will illuminate any "target" that wanders into that area though. When the new camera goes in it will provide full area IR lighting, I hope.
My thoughts on the Tendelux versus the CMVision, granted the Tendelux is lower power than the CMVision -
Both are nice little units. They both deliver wide fields of illumination that appears to be pretty even. Bang for the buck goes to the CMVision in my estimation though.
The Tendelux only has four emitters, so if one fails, you lose 25% of the light while the CMVision has at least twenty so if one craps out it might not even be noticed.
The Tendelux comes painted black, not exactly a popular color on the outside of houses. I sprayed mine white to blend better, white soffit, facia, gutter and downspouts. The CMVision comes in white.
The Tendelux does seem to be a metal housing and mounting bracket while the CMVision are all plastic except the mounting plate and gooseneck which are metal.
They both appear to have stainless hardware.
The Tendelux mounting system is a little harder to work with, the screws to lock "pan" are under the light housing and have to be tightened before mounting the light, not even enough room for a right angle driver. The CMVision is fully adjustable with the light, itself, in place.
