Those flashlights use out of date 5 mm LEDs originally designed IN THE LAST CENTURY!!! (~1995 by Nichia). Because multiple LEDs are difficult to build with reflectors they are all flood no throw. (I have seen reflectors on multi-LED 6V lanterns with the big 4 inch heads.)
9 LED means the flashlight has 9 of them, 32 LED means have 32 of them.
Those LEDs are also very dim. About 3 lumens each. So a 9 LED flashlight is ~27 lumens, a 32 LED is about ~90 lumens.
They are also very poorly heatsinked. When used for short periods of time such as looking for something dropped under a desk is fine. But hour long walks would burn up the LEDs. Some tests have shown thy last only 20 hours in continuous use.
Plastic 5mm LEDs cannot be heatsinked, since plastic does not really conduct heat (meaning very badly). When a 5mm leds only lasts 20 hours it is overdriven. Since it is overdriven there is too much heat trapped inside which cannot get out.
I would stay away from them except for very casual use.
I agree 
Dollar stores usually have them on sale plus a package of batteries on the way out costs you $2 and no wait for shipping. No need to go to ebay.
Here are some comparisons of brightness of a good single LED.
Luxeon (2000) 30 lumens 50,000 hours.
Luxeon III (2002) 75 lumens 50,000 hours.
Luxeon IV (2003) 200 lumens 1,000 hours.
Cree XRE P4 bin (2005) 80 lumens 50,000 hours.
Cree XRE Q5 bin (2008) 120 lumens 50,000 hours. (200 lumens when overdriven.)
Cree XPG (2010) 120 lumens 50,000 hours.. (280 lumens when overdriven.)
Cree XML (2012) 240 lumens 50,000 hours.. (Almost always overdriven to 800+ lumens.)
Dates and numbers are approximate. I'm going from memory.
27 lumens for 9 LED? Meh!!!
You can find old stock Cree XRE for not much more than the 9 LED versions at DX or ebay. They are usually just listed under the bin rating - P4, Q2, Q3, Q4, Q5.
