Question: Where is the on-off switch?
Document: Just what my grill needed. Feels sturdy and like the push button on off switch and rubber c clamp. Have it mounted on an oval handle and it does not move.
Loved it until I let it get too close to the grill. Now it looks like something Dali would have designed. However, before my faux pas, it worked very well. I wasn't able to find out how it would last once rained on, after all, I am too lazy to cover it or take it indoors when not in use. Nice light head, lots of light. Switch is conveniently placed.
this product looked like it was built pretty well but started rusting within 2 weeks.
this light is bright, nice clamp, very solidly built and it only takes a few AA batteries (if memory serves...it's 3 AAs, but it's outside and I'm not getting up to check). I've used it moderately, probably twice a week for a month, and the batteries are still holding up.
this grill light is perfect. we like to grill outside even in the winter. ..with the darkness arriving before 6:00 now, this light is exactly what i needed. it attaches easily, looks good, and works well! so easy to use and directs the light where you need it. i'm so glad i have it....should have had it sooner.
i love this bbq grill light, considering purchasing a 2nd one. I do alot of bbq smoking and have a table set up right next to the smoker, so its very convenient to have this grill light right there since ive been too lazy to put a spotlight off the back of my house. Ive used this light at 3 different grills, didnt have any issues attaching the clamp or using the magnets for the matter at any of the grills.
i expected it to be brighter and I especially expected the batteries to last longer. . even though I turned the light on while turning and placing and off while cooking the batteries exhausted to give very dim light after only a few minutes and I started with brand new batteries.
also plan to put a plastic bag over the battery compartment when leaving unit out in the rain.
You need this if you grill at night. Don't leave it out in the weather. Cover it or take it in at night. Love it I have had other cheaper ones but they broke or didn't spread enough light across the grill surface.
Works well, casts a decent amount of light. The flex cord is a little weak, if that was improved on it would be very useful. If I had it to do over, I'd but something different.
Answer: Rubberized switch on the back side of the battery compartment
