Sandbags for monolight and reflector stands.

[tecboy]

How many pounds of sandbags do I need for monolight and refector stands?

Buy C-stands, so that the sandbags are easy to put on. Check this out : Strobist: Without Reservation: A Recommended Gear List

How much weight you need depends on several factors - build quality of the stand, the stand height, size and weight of what is mounted on the stand, and if/how much wind there is.

Most of my 'bags weigh 15-20 pounds. I buy them empty from eBay and fill with clean playground sand; $5 for 50 pounds at the hardware store.

I used everything from workout ankle weights to trash bags with water in them.

Some of the nicer weight bags use steel shot instead of sand.
Some weight bags are made for using water. The water can be poured out so you don't transport as much weight.
A gallon of water weighs 8.35 pounds.

Many sew, or have someone else sew, weight bags for themselves using a wide variety of materials.
