The Bainbridge infrared heat bulb range is designed to produce a broad warmth and optimal heat conditions, while utilising red light to lessen disruption at night. Ideal for keeping warm (or brooding) young chickens, ducks and other birds. This is especially important for young chicks that can't maintain their body temperature during the first few weeks of life.
Main Features:
- PAR38 bulbs are more efficient compared to standard glass bulb designs due to the built-in reflector system (note the metal sides in the image on this page).
- The heat promotes warmth and activity in poultry, reptiles, small animals, and other livestock.
- Designed with a reinforced hard glass construction.
- Available in four (4) different strengths to suit a wide range of animals - 50W, 100W, 150W & 175W.
- Suits E27 socket bulbs (screw type).
Help Selecting Bulb Wattage: Here are some considerations to help you choose the right bulb wattage. However, please read and follow the instructions of the products you are using. Use that information ahead of any information provided on this page. Information on this page may be incomplete or have errors and should not be relied on.
✅ 1. Holder Capacity.
-
Be sure that the Bulb (lamp) wattage doesn't exceed the capacity of your lamp holder
– For example, our Shoof lamp holder has a max capacity of 175 watts, but the max varies according to the holder used.
✅ 2. Brooder Size
-
Small brooder (e.g., storage tub or 1m² area):
– Usually, 100–150 watts is enough. The height of the brooder will determine the required wattage. The higher the brooder, the higher the watts needed. For short enclosures, even 50 watts might be enough. -
Medium to large brooder (1–2m² or more):
– A 250-watt lamp is commonly used.
✅ 3. Number and Age of Chicks
-
Newly hatched chicks require a temperature of around 32–35°C at floor level, directly under the heat source.
-
Older chicks need less warmth each week (drop by 3–4°C per week).
-
More chicks = better heat retention (but still need a strong enough heat source to start).
✅ 4. Ambient Temperature
-
In warm climates or heated rooms, lower wattage (100–150W) may be fine.
-
In cold sheds or garages, you might need a 250W lamp or two lower-wattage lamps.
-
Always check the brooder’s temperature at chick level, not just the air above.
✅ 5. Lamp Height and Type
-
The higher the lamp is hung, the more wattage is needed to maintain warmth at the chick level.
-
Infrared lamps are more efficient and reduce light stress (red spectrum preferred over white).
✅ 6. Thermometer Use
Place a thermometer at chick level directly under the heat source. Ideal starting temps:
-
Week 1: 32–35°C (90–95°F)
-
Reduce by ~3°C (5°F) each week until fully feathered
If chicks are:
-
Huddling together directly under the lamp – too cold.
-
Avoiding the centre/heat zone – too hot.
-
Evenly spread around the brooder – perfect.
