I plan to do star photography, will this lock in bulb more for 30 minutes or so? I'm not holding a button down for that long :)

You simply set the timer to the length of the exposure you want then press the "timer start/stop" button. Or you can press the "Hold Button" and slide it froward. The will start the exposure and the timer will count the seconds or min. for you. When you get to 30 minutes, which seems rather long for astrophotography with out an EQ mount, you would slide the button back and the exposure stops. (FYI:Your camera would have to be set to "Bulb" for that kind of exposure:-) Clear Skies - For more on astrophotography visit Dakota Starry Nights on youtube

Unfortunately i didn't end up keeping this bulb. I bought 3 different ones and the one i picked was from g7. What i found with all of them was there was a short delay with start up its nothing be worried about.its hardly noticeable and is about 1/2 second.

This is a light modifier that attaches to an existing studio strobe, such as the NEEWER® 180 Watt Professional Photography Studio Strobe/Flash. I would not recommend it for a continuous light "bulb" as it would get very hot very fast.

It has a bulb exposure -- you can press a button and lock it for a curtain amount of time. It doesn't have a timer, but yes you can do night sky shots with it.

Definitely. Set your exposure to bulb and then you can set whatever length you want on the remote. I've gone up to 10 minutes but it'll go longer.

Thanks for the info. I hope to goodness that the lamp life is not 3,000hrs! I've been waiting years to buy a projector that doesn't require rip-off bulb replacements. My own HS201 is on a UPS truck at this very moment, waiting to be delivered to my house...

It depends on how you use it. a) you must have the right (gu24) base / socket holder b) the bulb may take a bit (1 min) to warm up - if the need for light is for a short period then probably use a regular bulb - however if just placing outside (day/night sensor) should be fine.

hello thomas, there is no delay for this led bulb. (instant on when power is switched on) also be advised these ecobright led bulbs are not designed for totally enclosed fixtures & are non dimmable. these bulbs are well built & are bright & a bit bigger around than some others. regards, neil

It works in Bulb mode. Hit once to open the shutter and again to close it in bulb.

You set the camera body on Bulb and you can set the amount of time the timer keeps the shutter open. 2-7-12 minutes, etc. which is the same as open continuously.

No. It's an LED that's soldered to the wiring. But the LED should last around 10,000 hours, so replacing the bulb should not be an issue.

I usually give it 3-4 hours ahead of when I'm going to be taking photos...it's more of a "play it safe" thing I do. So sorry, I can't give you the exact time it takes. Normally, I plug it in the night before I need it.

I'm not quite sure what you mean by "lock". For me, I set the shutter speed on my camera (which does have a bulb option). When my camera shutter speed is on the bulb setting, I can press and hold the button on the remote for as long as I want to determine the duration of the shot. Does that help?

I use bulb setting as well. This feature works best when you have a remote that is capable of being locked so you don't have to personally hold open the shutter for the duration of the shot.

if you cover the photo cell(block light from entering the cell), the light comes on in approx 1-2 minutes. uncover the cell and it goes off in aprrox 30-45 seconds. this is what you do to check if light is operational. if light does not come on and there is electric power to light, the bulb is probably burned. if the light stays on, the photo cell needs repalcing. instruction usually accompany the light when purchased.

Yes. Set camera to bulb mode in manual exposure. Then you can set shutter time with the remote.
