Blue Torch IBT-20 and Laser Pointer ILP-20

Blue Torch IBT-20 and Laser Pointer ILP-20 ? Did anyone try these?
Are they actually usefull or just for 'geeking'

Blue Torch IBT-20
This tiny snap-on accessory gives off a strong blue light when attached to your Sony Ericsson mobile phone. Use it in complete darkness, and you will be surprised at its strength. To make sure you have it with you at all times, hang it on a key ring or phone bag.

Laser Pointer ILP-20
An impressive mini laser pointer to impress your audience. Giving a presentation, you can use this tiny accessory to point to elements on a large screen.

geeking :robot:

I've seen the torch in action and it's not that bright.
I can buy a pen/laser pointer for a 3rd of the price SE is offering.
Furthermore, it's gonna be dorky looking when you do a presentation holding a PDA/phone while pointing to the screen. For this, pen type should be better.

Actually, just getting the screen to turn on gives a pretty bright blue light, not dissimilar in nature to the flourescent work torches you have for cars.

Used it many times to locate stuff in dark hotel rooms -- bed, woman, woman's glass of water on the floor, ... etc 8)

yeep agree the pen is probably useless as I would not want to point my p800 anywhere...

but that torch...if its very small to fit around the keychain...that could be a nice gimmick!

I've got the torch, and the light is surprisingly powerful in an unlit room. It is much brighter than the light from the P800 screen, and is very small and therefore very portable.

How long have you been in the said unlit room?
IMHO, after a few minutes (depending on your carrot intake),
any light will seem really bright, the screen certainly blinds me...

... or is that the vodka?


PS. You do note they [SE] say "in a really dark room", so trying to augment, say, a streetlamp is probably not useful other than to give you some colour back under a sodium light (cf: cutting the wire in "Abyss").

------------------

I used it on several occasions to show friends round our new house extension, which at the time did not have any electricity in it. It was immediately bright enough for that use. In daylight the light is disappointingly dim - I'm not sure why it is so much brighter at night. In fact, my kids told me that it was too bright!

Well, human light perception shifts drastically based on ambient conditions; you can see how fast the camera drops off as you reduce the light levels, whereas the human eye compensates fast (by dilating).

Most humans come to full night-vision in about 15 minutes, although some are faster and some are slower. Most of this happens in the first 30 seconds or so -- note how a bedroom is dark when you first get in bed, but if you wake up later (for whatever reason) it is normally pretty easy to navigate, albeit in black and white.

In normal light, a low-power source, especially at the blue-end of the spectrum will be outweighed by red and yellow sources such as the sun.
In very low light conditions, however, it is the only light source, so it seems brighter.

Blue light has a lot of energy for it's intensity, so at any given power it seems brighter, this is why night-ready environments (such as fire-control or C&C on a battleship) use red lighting in night ops to reduce the time it would take the eyes to switch back to full night vision. For the same reason, emergency vehicle use a blue light (in Europe anyway) because it is more piercingly bright.
