    WTB: low power 589nm

    Basically I want this color for my home made laser lumia show. I know this color will look great on the wall! High power isn't important, it's a bright wavelength so I think 10-20 mw would be fine. Adjustable power/focus would be nice, and yes, I know all this suggests a lab or tabletop laser...

    Help! I need 405 vs 445 comparison pictures

    I need to decide between a build that will feature either a 500mw 405nm or a 1.2W 445nm. I don't care about burning as much as beam visibility (I know either one will pop a balloon with impunity). Yes, I know the 445nm will be brighter, but I'd really like to see comparison pictures of the...

    FRYING a camcorder

    I have a very paranoid and misguided neighbor who thinks I've been throwing stuff into his backyard as revenge for his dogs which bark nearly 24/7 (it's a long, sordid story, but I'm trying to keep it brief here). Anyway, because I had the audacity to compain to him about it, he assumes its...

    Idea/suggestion to make ALL reviews more helpful!

    I just had an idea... When people post reviews, they often have pictures of the beam and dot because, well, it's cool and everyone likes to see those pics :-) But the problem is no two beam shots are created equal! Depending on the environment (light/dark, was there smoke, fog or dust around...

    Wicked Lasers Spyder III ARCTIC - my review

    So after 7 months of waiting (I ordered it in July), I finally got my much ballyhooed Arctic yesterday. There's been a lot said about this laser and Wicked Lasers, so I'll keep this brief and to the point: I love it. The infamous Lightsaber host really is a work of art, and it's a very solid...

    Great use for those "star filter" pen tips

    So I admit it, I was suckered in by the ritz & dazzle of those ads for pens with multiple screw-on tips, each with a different diffraction grating. The pictures are so enticing - but when I finally got it home (a 30mw pen with 6 tips), within a few short minutes you kinda realize there's not...

    Sell me your 405nm (violet/purple) laser

    Looking for approx 50-100mw, not for burning. Would like it to be focusable and have a true on/off switch (not momentary "hold it down.") Prefer "portable" over a pen since I plan to use it with a long duty cycle. Let me know what you've got!

    What power 405nm = 532nm power (brightness)?

    Let's say I have a 10mw green. What power 405nm do I need to match the brightness of 10mw 532nm? I'm about to buy my first 405nm handheld and I want to make sure it equals the brightness of approx 10mw green (for a lumia wheel show).

    How does mw rating effect battery life?

    Does a 200mw laser actually use twice as much power as a 100mw? Is there a "sweet spot" for brightness vs battery longevity? I'm not interested in burning, just keeping brightness for as long as possible. Or does all this depend on the kind of laser (i.e. green behaves differently than red...

    How does (or should) the battery effect a decision on which handheld to buy?

    So I'm looking through the various choices on 405nm handheld lasers to buy (this will be my first one) and there are a LOT of options. They come in all shapes and sizes, and naturally many of them take different kinds of batteries: AAA CR2 CR18650 CR123A Are the most common. But which to buy...

    Can a battery powered pen be converted to a plug-in?

    Is there any way to rig up a battery powered pen/portable laser to be plugged into the wall? Presumably with a DC adaptor... I'm guessing a pen that's powered by 2 AAAs would need a 3V DC adaptor... but how would you convert it? Is it possible?

    What should I do? Pen or lab laser?

    So i'm interested in getting a 5-10mw laser in both the 589nm (yellow/amber) and 437nm (light blue) varieties. They would both be used to run my little lumia wheel show at home, which I am currently running with ~7mw green. Since the yellow and blue lasers have a similar brightness to the...

    Can I use 3D glasses as temp goggles?

    I just got a 150mw green and am still waiting for proper goggles. However, I was playing with a pair of red/cyan 3D glasses and know that red blocks green, so I put them on... and if I look through the red lens with one eye, the green dot becomes a barely visible spec. Does this mean I am...

    BATTERY REVIEW: Sanyo AAA 1000mah rechargables (WORLD'S BEST BATTERY)

    Being new to lasers and laser pointers, I thought it would be a good idea to stock up on AAA rechargables, as it seems these are the most common battery used in pointers. I personally was running a 5mw green to fuel my "laser lumia" show. To keep the pointer running, I taped down the "on"...

    Need help: How do I power this laser?

    So I bought this on ebay: eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices And I have no idea how to power it. The auction said "with DC power supply" so i took that to mean it actually CAME with a power supply! I have zero electronics skills...

    my super simple, totaly ghetto lumia wheel

    I love the "lumia wheel" effects, it's always been my favorite laser effect of all, and after a little hunting around and educating myself, I came up with this: zzRog57JS58 [can someone tell me how to embed YouTube videos here? I tried the embed code but it didn't work] Here is a link to the...

    Does a cooled laser run longer?

    I'm currently using a garden variety 5mw green pointer to fuel my lumia wheel show (and by "show" I mean I project it on my living room wall/ceiling all night long). To keep it running ive had to use rubber bands to keep the "on" button depresed and even though I have no idea what the duty...

    Can a "line" laser be converted to a "dot?"

    I'm interested in these red lasers on ebay: eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices 650nm 50mW Industrial Red Laser Line Module Power Plug - eBay (item 180521164574 end time Oct-13-10 09:02:48 PDT) But I noticed they project lines, not...

    What power levels match the visibility of different colors?

    I hope that title makes sense, it was tough figuring out what else to call it... Basically, we all know that a 5mw green looks much brighter than a 5mw red or blue - so the question is, what power levels basically match the various colors? Does a 30mw red match the perceived brightness of a...

    WTB: Laser modules (used or i'll pay you $$ to build me one)

    So i have a lumia wheel that i'm driving with a cheap, 5mw green pointer with the on switch taped down. Very ghetto, I know. I'm very new to the laser world, so bare with me. Apparently what I really need is a laser module - a laser in a little box that I can plug into the wall and run on...
