Zoo Med Nocturnal Infrared Heat Lamp (150 watt) True red glass, not painted or coated! Zoo Med's spot refl ector focuses more heat into your enclosure and minimizes nighttime glare. Ideal 24 hour heat source for all types of reptiles, amphibians, birds or small animals. Very little visible light provided so as not to disturb your animal's sleep patterns. Excellent for nocturnal viewing of all types of captive animals.
I've always been a big fan of the Zoo Med product line and have used their 150 watt bulbs for many years. I think they throw off a good amount of heat for my large terrarium needs. Unfortunately I think Zoo Med has either changed the manufacturing process or more than likely switched to a different bulb made "elsewhere". For many years I could go 5-6 months without purchasing bulbs. The past 2 years or so it seems the bulb lifetime has been cut in half but the cost remains the same. I am experimenting with other bulb manufacturers to see if they have more life expectancy.
