How much mW would it take to ignite a candle? (Light it) using a 445nm laser!
My 1.5W can do it so so .. todays 2W builds should do it.
Relighting seems to make more sense.... lighting a candle thats never been lit seems like the white wick might be a tougher job.... then again, I guess it probably would turn black rather quickly from the laser itself, then absorb more light and light up....I was able to relight a wick with a lazerer 1.2w stick. If you hold the laser straight over the candle the smoke will interfere, however.

I'll have to try this with my 1.7w....
Best guess would be around 1300mw +/-100
The beam specs arent as good.... personally I'd rather have a more "laser like" beam over a higher power "flashlight like" beam...
I cant say from personal experience, but I've read about them/seen pictures and I personally like the tighter beam made by the 3-element lens. At 10yrds its about twice the size as a 3-element lens dot at the same distance. It still definitely looks like a laser, but the beam specs are definitely not for pointing long distances or keeping the laser like profile.
These G-2 and G-1 lenses are definitely made with maximum output power in mind, but not so much the beam quality... so if you are only going to use your laser as a short distance burner, then go for it... Any lens that has 1 element is going to make better power than a 3 element lens. I think the 9mm diodes have a single element glass lens, which means more power, AND they have a tight beam profile.... Not certain on that but I have seen others talking about it on here...
