Question: Does this have an on/off switch on the back? Is the switch a push button or a rocker switch (I/O)? Is it covered by plastic?
Document: No on/off switch, 12-14 inch cord, bulbs were broken, the directions just want you to figure it out, and the most irritating for me is that the bolt for the stand does not catch on stripped plastic nut.This is the first time I have been disappointed with my Amazon purchase.
This means I would have to stop to tighten them back up. If they had the wing nuts, this would be less of an issue and less of an annoyance. But, other than that the lights performed as expected the entire time. It would be nice is there was an on off switch as others mentioned but this really wasn't an issue for me.
I also received this light broken. The external mailing box was intact, but the  box inside had obviously been dropped  prior to packing. It was frustrating because whoever boxed it up, had to have seen the damaged box and could hear pieces rattling around inside. We opted for a refund, but Amazon was great and timely to get our refund back to us.
The light part works very well, however the shell and the stand is made of very cheap material. It is very tricky to get the protection cage on the light, and a small piece of plastic that is on the rim of the light cover broke off. I really needed the light and it was a minor part to the light the helps hold it on so it was still usable. The light that it puts off is very bright and from that aspect it is very usefull.
Good light but there is no on/off switch. also the bulb arrived burnt out. I was very grateful for the spare they mailed with the product however.cant beat it for the price though.
It is a strong light! Looks like the picture, and generously comes with an extra bulb. I purchased two, and 1 of the bulbs was busted but I still had another one to back it up so it was nice. These have VERY SHORT cords, so make sure you have an extension cord handy... but don't plug an extension cord into an extension cord- that will start fires. These lights definitely have the potential to start a fire so don't leave them on too long.
I can't understand why this light has a 4 star rating! I went with that in mind when i purchased it. The worst thing about it is the flimsy tilt/adjustment mechanism! In the one pictured, there is a wide, black plastic, &#34;collar&#34; in which the adjustable tilting mechanism would easily rotate and it is mounted with two bolts and nuts. What you get is a light that a 5th grader could have designed the tilting mechanism as I received.
No complaints, very satisfied!!!! Extra bulb is worth 3-4$, which makes the price even better. There is not a on/off switch, but not a problem for my application.
Light arrived overnight . Unpacked it only to find that the hinge for the lamp lens was broken. Also there is no on/off switch. Spend 5 bucks more and get a better light. They got one star because they refunded my money without a hassle.
This is a pretty cheaply made light, with no power switch, and is a bit of a pain the butt to assemble. The light bulb arrived broken but they did thoughtfully include a spare.That being said, it did stay lit for a project we had. It gets so hot that it doubles as a bug zapper.
Answer: no
