To believe those things are safe is a fool's denial. Yes, paranoia will get you far. |

You know what a Radiometer is, I have two of them.If I set them in the Sunlight or near an Incandescent light bulb, the little black and white vanes spin around fast.If I set them near a flourescent light, the vanes do not spin around at all.Light, real Light has mass and pressure. That isn't what makes the vanes go around. If it were light pressure, both sides of the vanes could be the same.

Indeed - and instead of being in a compact, eminently manageable form and amount, it is spread out en mass across the atmosphere and landscape, affecting all the life on the planet, and unable to to be controlled or avoided. Oil pushers make the same goofy arguments about solar panels - too many toxic elements in a panel. Same retort applies. |

Hard to imagine, but remember - there are billions of us, using this stuff at a breakneck speed. |

I just use the simply "common sense" test. Pretty simple IMO, hold up an open book and look. Which type of light makes it easier to read? Until they come up with an even better type of lite that emits more lite, my majority of bulbs will be the usual. The problem is that incadesecnt lights are truely a full spectrum device. They emit waves from far infrared (heat) to near ultra-violet over a continuous spectrum. Most of their output is far infrared, about 90% of the total, and by the time they get to ultra violet, it's negligable. Floursecent bulbs emit only ultraviolet light inside, and use that to excite phospors on the outside of the bulb. They absorb most of the UV light, and emit single color light. Household bulbs use a combination of the 3 primary colors of light (red, green and blue) to produce what looks like (but really is not) full spectrum light. Good explanantion, that made it make sense even too me. LED's also work the same way, combining but they emit the colors directly.. Both are combined in such a way as to look white. The problem is that the colors are generally set up to mimic daylight, (the light of the sky on a clear day), not sunlight. The human eye is used to seeing sunlight, and is more comfortable reading with it. OK, copy that too. Can you explain this for me, with the combination of your radio knowledge and these different bulbs etc. Why in your opinion won't anyone replace my LED (am I saying that right?) on my modded 394. I want that crap green gondo and replaced with the indiglo blue like RadioLabs do with their 398/909. I asked them and never received a response which was kind of surprising in how good they usually are in answering emails. Are you familiar enough with what I'm asking - is it even possible? I know it can't be for the lack of room because the 909 is a portable and the 394 is a desktop. Can't hurt to ask you - no one else knows apparently. :-) Incadescent light is the most comfortable for reading, being more like sunlight (actually it is even more red). Ok, would that explain this then? I used to have a reading lite that was red, it wasn't a hot red or anything - but at least "for me" for some reason that was the best reading light I had. As far as efficency goes, incadescent light is about 10% efficent, although there are more efficent and longer lasting bulbs around, they have never really been markted effectivley. LED lights are about 25-30% efficent due to problems with heat dissipation, the fact they are DC devices in a world with AC power and so on. There have been claims of almsot 50% efficency in the future, but so far they are just claims. Flourescent lights are around 35% efficent, which currently makes them the leader in lighting. It's IMHO actually a false claim because due to the difference in spectrum output, I find that I (and my family) all need higher power lights to read if they are flouresent. That's why although I've been using CFL's for 13 years or so, we still have reading lamps with incadescent bulbs in them. Exactly. I tried the newer ones for reading, it just wasn't going to work for me unfortunately. My hope was to use two of them in front of the house with each light encased in its own housing. I guess because of the differences of temperature throughout the day into night/ cold/ humidity etc. they didn't last five months (I think) and they're too expensive to use them if they're not going to last longer than that. What I am hoping to see is a varation of the 360 degree LED with improved efficency. These are similar in design to flourescent lights. The LEDs are encased in a block of plastic, which instead of clear like traditional ones flouresceses (glows). The ones I have been using to replace radio dial lamps glow brightly in a daylight white color in all directions, I'm hoping to be able to buy them in "warm" (redder lights for reading) in the near future. Yep, refer to earlier on my post about the red for reading. I've also noticed on CB's nowadays. It seems to be the fad of using all different kinds of LEDS on the radio and Nitro Knobs, from what I hear they are pretty expensive. There are all kinds of youtube vids of these radio modded out, I must say they are somewhat eye catching if anything else. :-) Until then, IMHO you are wise to replace all of your incadescent lights for general illumination with flourescent ones, the "regular" kind being cheaper to maintain than CFL's, but to make sure you have a large supply of replacement bulbs for your reading lights. Copy that. Thanks Geoff. I learned a little about lights. |

To believe those things are safe is a fool's denial. What things? The bulbs or cell phones, or both? FWIW - whenever I use my cell I use the speaker mode. I feel I know enough to not TX right on my head. Everytime I see someone using their cell in that matter it crosses my mind. And the BT technology, I'm not real familiar with how that works, I have an idea though. But using anything like that - that someone can copy what you're saying isn't a good thing IMO and even worse is that if it's on (though you're not using it) anyone with a lick of common sense and the correct piece can listen to everything you're doing / saying / in your vehicle. I suppose many people either don't care or don't know, it has to be one or the other IMO. |

I know it can't be for the lack of room because the 909 is a portable and the 394 is a desktop. Can't hurt to ask you - no one else knows apparently. :-) I had to go find a service manual for it to answer this one. There is a row of surface mount LEDs soldered to the logic board. On top of this is an LCD screen. The manual goes into no detail, so I have no idea of how it is mounted or connected. If, and I say if, the LCD is just stuck on there with some tape or glue, and is connected to the circuit board with a cable, then you could probably remove it without damage, and replace the LED's with another color. or put an opaque strip over them and a new strip with a different color. That may be a little more difficult because you have to find a place to draw power from. Then you just stick the LCD back in place and it works. :-) More likely the LCD is instead soldered to the board. It may be surrounded by a metal shield as LCD's are very noisy electricaly and it could interfere with your reception. The shield may be soldered to the board too. Removing soldered on shields is difficult and removing soldered on LCD's is time consuming, which translates to expensive. By my count, there are at least 28 pins or connections on the bottom of the LCD. So I expect that the cost of replacing the LEDs is very high, far more than the radio is worth. When the radio was relatively new, if you needed to replace the LCD or an LED, you would just get a new logic board from Radio Shack. Now you would have to find a dead radio with a working logic board, such as one that had the front end destroyed by lightening and use that. I hope that answers your question. Geoff. -- Geoffrey S.
