Hi Mike, as a newbie to ceramic heat globes I have to confess I was
disappointed with the amount of heat put out. I brood with low heat (but lots of nest insulation), so I was after something that would produce similar heat as a 40w infra red globe.
Unfortunately my 60w ceramic put out I would say about half the heat as the infra red globe. I'm not sure of the style of heat produced but all other things were equal (ambient temp, style of brooder, amount of litter, distance from floor) so I just feel the ceramic globe isn't as efficient as red.
Now I'm not at all versed in how these things work, so there may be some good reason why 60w ceramic isn't as warming as 40w infra red, but that's about where I stand...
Of course if wattage doesn't matter (i.e. if cost of electricity isn't an issue) then I would go with ceramic as it stops teaching chicks to follow light, and allows them to be taught ordinary day-night rhythms including to go to bed at dusk.
Just my thoughts, hope they're not too unhelpful!
cheers
Erica
