While I understand your thought/desire, and the fact that this at least has a safety switch is an improvement....however, the switch only works if the angle of the light changes. If it happens to fall/land somewhat straight down....a) it would light straw or shavings in no time at all and b) landing 'upright' so to speak would mean the switch wouldn't shut it off.
I used to use a heat lamp in my brooder (because they were inexpensive & covered a larger area). Despite using a secondary tie-up in addition to the clamp...my young fliers managed to knock it down...and it burned part of the large wooden brooder box (4'X6') Fortunately, I caught it before it did more than smolder (plus, it happened to melt the corner of a waterer, so water slowly dripped and moistened the bedding...so smoldering only, no flame-up. I felt someone was watching out for me that day, as I could have lost all my babies, maybe even the house. I was VERY lucky, - didn't lose anyone. However, I will never use a heat lamp again. Not even a month after that, the farm down the street lost their whole dairy barn and a couple of cows and all their baby calves as they were using a heat lamp for a newborn calf (2-3 days old), and the heat lamp got knocked down & the entire barn (plus all the hay in the loft!) burned. This was a couple of years ago, and they just finished rebuilding this past summer.
So, again, I will never use a heat lamp again! I won't dictate to others, but I WILL encourage you to use
safer options.
