Question: Is this a 2 prong or 3 prong plug?
Document: Have to attach the whole clamp section oneself.Really need 3 hands to attach - one to hold the 2 pieces that go around the base together, 1 to hold the ball in the hole space between the 2 pieces, and one to attach the screw to tighten and hold the two pieces in place. Mo tools necessary but 3 hands will save a lot of frustration and time retrying to juggle the parts to attach without one or the other falling.Now I realize why the clamp won't stay in different positions.
That means the 6 foot long power cord is very thick (18/2 SJT) in comparison to other competing clamp lights.
The ceramic base comes apart easily from the dome piece, every time I unscrew a bulb it is a problem. I purchased two of these and after 2 months, one just stopped working. At first it was sometimes coming on and sometimes not and then it just stopped working altogether. Waste of money and just enough time that I can't return it. The second one is still working, for now.
My sheep were able to knock off the wire shield after a couple of weeks. That's the whole reason we purchased 2 of these - our sheep were getting scorch marks on their backs from standing under the heat lamps in winter. This is seemingly a quality-made product, but I was hoping for a lamp that the shield wouldn't easily be knocked out of. The search continues.I see other reviewers didn't like the clamp option.
very nice quality lamp housings for infrared bulbs, possess a stout porcelain base for the acceptance of the infrared heat bulbs allowing long usage of the bubs and not having to worry about some 'plastic base' melting or otherwise being a safety issue.I was able to leave these lights on all night long, keeping a substrate warm on a large scale fiberglass project, I am working on and they have served me well...extremely well even during very cold temps.
very good quality cone and protective bars, and even the ceramic is very good, but the clamp is not quite strong enough to hold up this heavy duty system as well as i'd like it to. it appears the clamp is an after thought. it could be designed much better, but this was mostly designed to be suspended (not clamped) for chickens.
this worked well for what i needed it for hope to keep useing it in the future the clamps a bit tricky
this lamp feels like it was made out of beer cans, and was dinged up and scratched upon arrival, but is sufficient for industrial use.
the lamp does it's job some say it is too thin but it works great for my hens and I dropped it with out denting it
porcelain ceramic socket keeps it from heating up good thing reflexs light good just did not know this product has lead in it
