These bulbs are the ultimate in incandescent reflectors. They are the perfect
bulb for those high ceilings and hard to reach places. If you are tired of dragging
out the ladder for the reflector replacement now is the time to switch to the 20,000 Hour bulb.
If you are wondering if you can use a larger or different reflector in your
canister we will give you the formula to figure it out before purchasing.
The designations of R20, BR30, BR38, BR40 and ER30 have a specific meaning.
All incandescent bulbs have a formula, so it is easy to figure how wide they are.
The numbers in the above stated bulbs is the number of 1/8" in the width.
So an R20 has 20x1/8" so an R20 is 2-1/2" wide, a BR30 (30x1/8") is 3-3/4" wide,
a BR40 is (40x1/8") equals 5" across and a BR38 is (38x1/8") 4-3/4" wide.
This formula is the same for all incandescent bulbs. Whatever the number designation,
it signifies 1/8". So just measure your canister across and you will know
if a certain type of bulb will fit.
