Does it have a reverse or blocking diode to prevent night time loss of electricity ?

I don't know? Prior to this unit, I had a sunforce kit (with a module) which rats ate the cable near the unit. I replaced the solar unit next to the original solar panel and wrapped aluminum around the power cable. Now it works great, being that I check it once a week.

No I use a charge controller for that function, I am making a circuit to turn the controller of at night as well.

You will still need a diode on your panel to prevent the battery from discharging overnight.

I am reasonably certain that there is no blocking diode on the panel. I bought two panels and put in my own diodes.

We do not include it. We use only high quality new cells that have negligible nighttime current loss. More power is lost across the diode.If you still want one contact us and we will send it for free. rich j

The light only turns on at night or whenever light is blocked from hitting the solar panel on it. Unlike some similar products there isn't an off-on switch. A mounting kit isn't included.

If you don't mind that the back light will not be constantly on, you can run this thermostat off of batteries. If you have the wire providing power to the thermostat, you can set the back light to stay on which is very nice at night. The batteries at this point provide backup, but then if there is no power, the fan in the house for the HVAC system wouldn't be working either. It's just there in that case to hold settings including the time and date.

Yes and no concerning built in diodes. It will prevent power from the secondary vehicle from feeding back into the primary vehicle but will not prevent power from the primary being back feed into the seconday vehicle. For example all the turn signals on one side (front/rear) and the dash indicator will flash. Also you might see a voltage drop and the lights on the secondary vheicle might not be as dim. Found this the hardway and ended up using four diodes also. One for each turn signal, one for stop and one for driving lights.

If this is like the six outlet fixture - yes. The "protected" indicator is always on. Not only a nuisance in a bedroom but small but continuous power drain.

There is a solar cell that turns it on at dusk or override to leave on all day and night

There is a circuit inside that looks like it includes 5 diodes, a capacitor and a coil. I have not drawn out the circuit,but I suspect that it makes up a reverse polarity diode, and a full wave bridge for rectifying 12VAC and a filter.I had one fail and just bypassed it to run strictly on 12Vdc and the LED array works again. I suggest that if you change to a 20 watt LED array, that you bypass this circuit too since it may not handle the additional current. I have used 4 of these fixtures so far and this is the only one that has failed.

Not sure what you mean by turn down. But if you mean turn it off, it only provides power when there is a load while inverting. So you don't have to worry as long as it is not inverting.

No, it has a blocking diode to prevent it from discharging the battery at night but no auto shut off

it keeps my battery charged and it has a red light that blinks on low sunlight and runs steady on full sunlight. the light goes out at night. I believe it does block discharge at night.the panel is poly not mono so parts of it might look different but still puts out 10w of power.

No, not on the light itself. This only has the sensor that turns it on at dusk and off at first light. You could install a switch in the circut, but it would not turn on during daylite hours, only at night.

With no load connect, it doesn't prevent the battery from over-discharge from a load. The solar panel can leach power back from the battery during the night though, and that is the discharge referred to that the controller prevents.

Only if the module is left in the "ON" state or the lamp is plugged into the other side of the module (bypass power "always on")

Yes the dusk to dawn switch can be bypassed. I have two lights on one switch and I am very happy with the quality and amount of light they put out.
