The par 38 bulbs are big,but you can buy compact halogen flood bulbs.The sizes are in eights of an inch,and there are Par 16(2 inch),par 20(2.5 inch),and par 30(3.75 inch) in addition to the par 38(4.75 inch) bulbs.Cyproz":2mw735rh said:Hey there. I need a basking/heat bulb for my bearded dragon. I know i can buy flood light bulbs but they are very big and im looking for something more compact. What bulb brands from pet shops do you guys trust?
They seem to give off the same heat but in a more compact bulb.
The spots are all too narrow,either 9 or 10 degrees or 16 for wide spot.The 16 degree wide spot can be made to work if it's mounted high enough above the basking area.The floods are either narrow,24 to 30 degrees,or wide,usually 40 to 50 degrees.The shorter bulbs have a slightly larger dispersion area,because they're higher up in the fixture(compared to a LN bulb in the same fixture),but the par 30 bulb is usually a par 30ln,which has a longer neck,so the dispersion is about the same as a equivalent par 38.I have all the spec sheets from Osram/Sylvania,GE,and Phillips if anyone needs exact model number or specs.Here's some links(PDF are downloadable):Taterbug":2imhud68 said:Be careful with the smaller bulbs (small PAR or Spot type) that the basking site is big enough. Some of them are much too focused and can generate a very small 'hotspot' and the rest would be too cool.
