Will this lock the shutter for bulb?

yes. presss the release once to open the shutter, and then again to close it. This is after the shutter speed on your camera is set to "bulb", of course.

it does have a lock, not familiar with the pentax about plugging it in. my canon uses a 2.5 mmm stereo phone plug, but I know they make different models for specific cameras, a great switch for the money!

there is a hole in the back of the unit to put the key (or any small object) into and push. This will release the lid where the bulb is. I hope this helps...

It should work, if worry about heat transfer if the bulb is to close unless it led or cfl.

This design is very much universal. If the part you actually depress separates from the bulb, it will not fit!

Mine is suppose to lock but does not. Do not buy if you are looking for security.

Yes it does. Just make sure you hit the enter button in the small control panel in the back of the fixture. The model is common to several manufacturers, the programs and modes will run as soon as you select them in some fixtures dependeing on the manufacturer and youll have the tendency to leave it run as such. Just hit the enter button and youll be ok. Some fixtures will need you to do so to lock the mode or programs in place.

If you set the camera on "Bulb", you can press remote button and slide it forward to lock the shutter open and remain open until you disengage the lock on the remote.

It is a bit difficult especially if you have big hands. It will lock but I had to use long curved needle nose pliers to get enough grip on the bulb.

No...it is a motion detector light only. You probably would need an electrician to put a timer on your light switch or you can buy a socket timer where you screw the timer into where your light bulb goes and then you screw the bulb into it. Good luck

Put the camera in rapid fire, manual focus, out the trigger in bulb... hit it once and the shutter will stay engaged.That might work.

Hello, according to the Nikon manual, "The shutter-release button on the WR-T10 performs the same function as the camera shutter-release button whether pressed halfway or all the way down." So if your camera supports bulb mode, the remote will act as the camera shutter-release to open and close. Thanks.

To your second question, you can hide the bulb by moving it to a side with the bulb fixrure

Yup. First, you need to use the Manual mode to set the shutter to Bulb (in Nikon D90, Bulb is right after the 30 sec.). Next, you push the button down and forward (toward the wire); it will hold the button down. Thanks for the question. I always thought the Bulb setting is in "A" mode but I just found out it is in "M" mode.

This product probably won't help if the bulb is truly jammed. I've never had a jammed bulb, but I have had broken bulbs that were stuck. In that case, I shut off the electricity and used needed nose pliers to grab the metal portion that screws into the socket and unscrewed it that way. This product does work very well for normal usage.

They have changed this bulb and the sensor no longer rotates. So, it is possible if you screw it in, it may face the back of the fixture. Not good.

The remote will work when you put your shutter speed on bulb mode, so you need to be in manual mode to do that. You aren't able to set that in auto so it will not work with that mode. All timer remotes (intervalometers) work that way.
