    Why do most projectors not use direct green?

    Thanks for the info. I guess the green diodes aren't useful until they bring the efficiency up.

    Why do most projectors not use direct green?

    From reading this forum five years back there was a lot of posts on how direct green diodes were developed for use in laser video projectors. I have google and almost every top end laser projector on the market still uses blue diodes along with color changing phosphors to get red and green...

    Osram PL 515 New 515nm diode?

    Seller isn't clear on whether that's a 515 or 520. Either way I don't trust that an ebay seller is giving you a real 515 and not a 520.

    Perception of 561nm differs?

    There are two rapid transition zones in the spectrum. One is from about 570-610nm, the other is about 475-515nm. 577nm would be nice if they make it at a low powered output.

    Perception of 561nm differs?

    561nm from what I see on the internet looks green with a hint of yellow to me. Yellow starts around 570nm, 589 is gold and 594 is orange. They'd need a 575-580nm for a true yellow.

    Lasers and clouds dangers?

    Clouds will scatter the beam so the power will be reduce quite a bit, unless it is a strong laser and a very thin cloud. Red will have a lot more cloud penetration than blue with the same power. Scattering of Light: by small particles and molecules in the atmosphere

    Need Help in Soldering? For Beginners - Solder & Flux 101

    Accessories such as a stand, clamps, tweezers, and desoldering tools, are the real wallet drain. The are essential though. Also don't get the thick stranded solder, or the lead free solder both suck. Also I find it easier to use a curved soldering tip rather than a straight one. It makes...

    ePay 3 pack laser LPM results

    Green was the least of the offenders surprisingly. Red was 117mw at 3v. Eh I guess they'll blind a few kids.

    My new M-140 laser lighter

    I would imagine the lighter would start to feel hot fast if it's acting as a HS.
