But can I put something on top of flashlight to decrease the size of light, that to me seam very logical, to simulate filter.

Thank you again, one more question How can I know the size of light on surface in millimeters or I must to guess from images. to me this has smallest : DealExtreme: $12.23 Flood-to-Throw Zooming Glass Optics Cree P4-WC 3-Mode LED Flashlight (3*AAA) and can I somewhat color the light in other...

Thank you very much, this is going better then I think it will go. I explore it, but how can I know size of light point at maximum zoom, because I need it to be as laser. From picture and overview I can't know this.

That is what I need but I can't find on the internet focus-adjustable LED flash light that light the surface like dot. Can you suggest me...

People, I got the message that I can't use laser for this project. How can I achieve this effect without laser, so 1-is there on the market something that will help me or 2-I will need to built it from scratch

So to conclude laser category II2 with output <1mw Cant harm your eye, but direct exposure it will. And somewhere on the internet I read "that lasers of II2 category is like lighter only direct exposure will harm your eye", is this true. I really need 100% safe solution for this project so...

can we conclude with power voltage of laser can/can't harm eyes (on fabric lasers).

Thank you very much wannaburnstuff. One more question how does power voltage influence on our eye(is bigger voltage more harm to eye or vice versa). I have laser 2A category on it writes : <1mw [made in China] wavelength 630-680nm avoid exposure, dangerous. what about it.

it does not matter about reflection I need that, that reflection can't harm your health(eyes...) In other words, you can think that I want to achieve light mouse point on screen.

what surface will it be hitting? Monitor screen. does it have to be at a certain power? Don't know what you mean by that :). Do you mean electrical power or something else.

Hello everyone, I am new to this forum and also to this question, Here is what i need: I am working on one project for which I need something like laser, but laser can harm your eye so I can't use it. (because it will reflect laser beam back to you from surface that will it hit). What I need...
