The short and simple answer is YES! However, achieving the same effect requires a combination of several factors: The LEDs should have as wide a viewing angle as possible. This will allow the light from one LED to "melt" into the light from surrounding LEDs and make them appear as a single, continuous light source. The LED string should be placed a reasonable distance away from the object to be lit.

This is a tricky question...if you consider the decrease in light output over time, there is no definitive answer. The light output of an LED is decreased by a deterioration of the semiconductors crystal lattice, whereas the light output of a neon tube is decreased by a deterioration of the fluorescent phosphours. Several factors contribute to the deterioration in both cases, including increased operating temperature, increased operating current, material contamination, etc.

Incandescent lights are basically electric space heaters that give off light as a byproduct. They are highly inefficient, transforming the majority of the power they consume as heat. Although LEDs are significantly more efficient in point-source lighting applications (i.e., not lighting up an entire room), they are still not even close to being 100% efficient. Therefore, although LEDs will also produce heat, it is at significantly reduced levels when compared to incandescent/neon systems.

Maybe a more appropriate question should be "Are neon tubes really as fragile as some make them out to be?". The simple answer to the revised question is NO! Neon tubes can take a surprising amount of abuse, but they are nowhere near as rugged as LEDs. While it's true that neon tubes can survive some fairly bumpy roads, it only takes a good shock to any point along the tube to destroy it in its entirety (rock hit, running over a cement parking block or speed bump that bends the tube, etc.).

This depends on several factors, including LED type/color, LED spacing, etc. In a nutshell, LEDs are significantly more efficient at producing light than neon tubes. If enough LEDs are placed together to match the light output of a neon tube, the power required to match it with LEDs will often be quite a bit less.

The short and simple answer is NO! However, that's not to say you can't produce the same colors using LEDs, only that there are certain colors of neon that are not directly produced by a single LED die. The trick is to combine the color from more than one LED type (red, green, or blue) in the proper proportion to get the desired color.

Have a careful look. If there are patches of blue glowing on the glass, probably with fairly sharp edges, it's due to electrons missing the anode and hitting the glass instead, making it flouresce. (Most of the tube envelope may even glow. -ed) Quite pretty, and you can play for hours, moving the patch with a magnet... (Don't electrocute yourself!) This kind of glow is common with beam tetrodes and is completely harmless. (This type of glow is by far the most common.

First, read the orange glow question above. Is the color you're seeing orange, coming from the top and bottom of the tube's "guts"? If so, you're OK. BUT... if the plate, or any part of it, especially in a power tube, is actually glowing red (even a faint red) shut the amp off at once and find out what the problem is. Otherwise, you will certainly destroy the tubes. You could also destroy other parts of your amp, resulting in a huge expense to repair it.

LEDs generally have an MTBF (mean time between failures) of 100,000+ hours, which means you can run them for 10+ years before they fail LEDs withstand shock, vibration, frequent switching and temperature extremes that rapidly incapacitate fragile neon tubes LEDs are significantly more energy-efficient than neon tubes, so you can run them longer using the same power If multi-color LEDs are used, the color can be instantly changed..

This is not only normal, it's a requirement of tube operation. This glow normally comes from the tube's heater, or filament, which heats the cathode so that the tube conducts properly. If you don't see this, and your amp doesn't seem to be working properly, check the amp in the dark (some tubes, esp. Sovtek 12AX7LPS tubes) have a filament glow which is very difficult to see. If you still aren't sure, let the amp warm up for a few minutes. Then, place a fingertip near each tube in turn.

No, you don't have to toss them just yet. However, a blue glow indicates the presence of some gas in the tube, which is not a problem in most situations. If you have noticed an increase in the amount of blue, then you might want to get a new set of tubes sooner than later. Too much gas in the tube can lead to bias failures, blown fuses, and possibly blown output transformers.

This technique is used to create neon signage signs and sculptures by bending glass tubes which are filled with neon or argon gases.

Glow engines are a hybrid between diesel and gasoline engines in regards to their mode of operation. In a glow engine, the catalytic action of the platinum glow plug coil is what ignites the fuel-air charge rather than a spark or the heat due to compression of the mixture in the chamber. As a consequence, the compression ratio used tends to be higher than in a gasoline engine but lower than a diesel engine.

For devices with RS-232 serial ports, it is customary to provide a status indicator LED for some of the signal lines (in particular transmit data and receive data). Often, these LEDs are directly connected to the line via just a resistor. As a result, anyone with a line of sight to the LED, some optics and a simple photosensor can see the data stream.

Most of the time, otitis media clears up with proper medication and home treatment. In many cases, however, further treatment may be recommended by your physician. An operation, called a myringotomy may be recommended. This involves a small surgical incision (opening) into the eardrum to promote drainage of fluid and to relieve pain. The incision heals within a few days with practically no scarring or injury to the eardrum.

No, and please don't try! LEDs of different colors have different electrical properties (current as function of voltage). Substituting different color LEDs generally results in either a very dim set (current too low) or one that damages the LEDs and quickly fails (current too high). It is generally dangerous to alter LED light strings in any way; this also voids their guarantee.

There are approximately 40-46 leds on the chip. For a detailed explaination of LED chip technology, please click here.
