Katie bar the door! This should be a L O N G thread.
I have several. First I recommend LED lights with a minimum of 3 watts output. There are many available from $29/pair at Sam's Club to way over $100 at a PD supply house. The LED lights use up a LOT less battery for the same (or more) light.
On the subject of light output, I prefer those with at least
150 lumen output (roughly 3 watts). The four watt (around 200 lumen) are really great, but use up more battery (DUH!).
The least expensive, yet well worth the money seems to be the Lumaforce-LF1 (currently on for $39.99 ea). Not anywhere near the 300 lumens advertised but well over 150 lumens (read that BRIGHT!). I - far - prefer the single function (on/off only) rather than the five or six function that you have to click through to get it turned off.
Another one that I found at Target is a "Life Gear" 4 watt (a bit over 200 lumen) for about $40 (don't remember exactly). A bit larger than the Lumaforce but still quite reasonable.
The all time best (but not a night stand size) was the Husky from Home Depot for $25. They discontinued then about six or eight months ago ( SIGH!
). They seem to expect instant sales bananza when they put out a product. It was available for less than a year (I scarfed up three of them - ZERO problems).
