This is ideal for maximum visibility on a tail light and can be quite blinding to look at directly (so don't). Likewise on the front, if you want to see where you are going a 1 or 2 watt LED bulb is essential, anything less is really just a light to enhance your visibility to others, not to shine a path.
Quarter Calendar Credit Hours. Some U.S. institutions use a quarter calendar, in which the academic year is divided into three terms, called quarters, of 10-11 weeksâ duration plus a summer session (considered the fourth quarter, but optional), a short winter term and other calendar breaks.
A quarter system divides the academic year into four terms, one per season, with attendance required in three quarters per year to total 32 to 36 weeks of instruction. A semester system divides the academic year into two terms of equal length, with attendance required in both semesters to total 32 to 36 weeks of instruction. There is often an optional summer session half as long as a full semester. A trimester system divides the academic year into three terms of 14 to 16 weeks each, with attendance required in two trimesters per year, to total 28 to 32 weeks of instruction.
