LEDs are of an advantage because they are available Con many colors today. LEDs are semiconducting diodes that emit light. The chemical composition of the LED determines the color of the light. Unlike conventional fixtures, LEDs do not need dimmers, but have intensities controlled by wattage. LED lights are much more energy efficient than incandescent or T-H lamps. While a household incandescent may be rated for 100 watts, an LED of the same intensity could be under 15 watts. One of their advantages to T-H and incandescent bulbs is that they do not require colored gels.
Aerosolized biological particles fluoresce and scatter light under a UV light beam. Observed fluorescence is dependent on the applied wavelength and the biochemical fluorophores within the biological agent. UV induced fluorescence offers a rapid, accurate, efficient and logistically practical way for biological agent detection.

This model of the chemical reactions makes several predictions that were examined Con experiments published by Jerry Goodisman in 2001. Goodisman notes that numerous recent authors propose chemical reactions for the lemon battery that involve dissolution of the copper electrode into the electrolyte. Goodisman excludes this reaction as being inconsistent with the experiments, and notes that the correct chemistry, which involves the evolution of hydrogen at the copper electrode but also can use silver instead of copper, has been known for many years.
Circuitboard Composition & Quality - For higher power LED strips, the quality and specification of the underlying circuitboard is paramount. Because high levels of electrical current must travel through each section, sufficient copper material is needed. Look for LED strips with a copper weight of at least 2 oz, and ideally 4 oz to ensure the circuitboard can handle the higher power - otherwise, you can become victim to voltage drop. LED Quantity & Quality - The efficiency, quality and stability of light output is directly determined by the LED emitters. Look for LED strip lights that place stringent quality controls and specifications on the LED emitters, and watch out for LED strips that claim a high power despite a low LED count, as this can indicate overdriving the LED emitters, leading to premature failure.

The power draw In foot (or meter) is almost always listed Per website an LED strip's datasheet. Not sure if you should choose between 12V and 24V? All else equal, 24V is typically your best bet. Read more here.
For larger LED packages total internal reflection (TIR) lenses are often used to the same effect. When large quantities of light are needed, many light sources such as LED chips are usually deployed, which are difficult to focus or collimate on the same target.
LEDs developed by Seoul Semiconductor can operate on AC power without a DC converter. For each half-cycle, part of the LED emits light and part is dark, and this is reversed during the next half-cycle. The efficiency of this type of HP-LED is typically 40 lm/W.[162] A large number of LED elements Per series may be able to operate directly from line voltage.
