if they have 1/10th the bandwidth, at one 1/10th power isnt that the same amount of power for that one focused wavelength as far as measuring power per each wavelength, anyway, even if it doesnt end up working as a standalone unit. I'll be interested to see if the phytochrome responds to the 780nm wave, and I'm pretty sure any extra 660nm red will be happily soaked up. I'd like to see an actual datasheet from these manufacturers it seems like theres alot of speculation about the power of these diodes. I read one place that the ps3 and xbox hd-dvd had the same laser diode in their laser head units, then at what i would consider to be a more reputable source of info on led's and lasers the ps3 laser diode was quoted at being 10-20mw MAX where the xbox diode was mentioned to be capable of >100mw.. I'm starting to think about thinking more economicly and use this old dvd burner laser here in front of me which produces 660nm and 780nm that can be seperately controlled and should be able to do >= 200mw output each and look at cfl's for a primary light source.

another little DIY project i found that looks worthwhile

...but you might want to swap the battery for a deep-cell, get a 1000w inverter, add cooling and 5 extra solar panels

If you're looking for a how-to this is probably not the right place. I'm starting this thread to discuss the possibilites of creating a poor-mans spectrometer from a webcam and a home-made spectragraph consisting of an old CD and cardboard tubing. This is probably going to be my first order of business. I am also proposing growing with lasers, that's right, I said it, Rating: 5
