I have this light (Night Rover xtra w/NiMH battery)
It is definitely bright enough for commuting in urban/suburban areas with some level of street lighting or other ambient light. I also ride 25mph+ on dark rural roads with enough with 10W high beam to see obsticals ahead. There are definitely brighter lights, but not many at this price. ($65-70)
But... The switches are notorious for having reliability problems. Do a search on switch and Cygolite. There are BKMs for fixing them, but they are temporary (involving re-bending contacts) The switches are driving me nuts now - Cygolite knows the problem and even will tell you the BKM. But the fix is temporary and Cygolite offers (at charge after warantee is over) a refurbishment, but you end up with the same switches that will fail again at somepoint, plus you loose the use of the light for several days when its getting repaired, so...
Mine (just the 10W) are now soldered in the permanently closed position and I turn it on/off by using the battery plug (and not longer use the 6W side which is too wide for seeing the road, but good for other drivers to see you a bit better from angles)
I am looking at getting a new ~$200 light (batteryspace) so I no longer have to deal with the switch hassle.
