High-power light-emitting diodes attached to an LED star base (Luxeon, Lumileds See also: Solid-state lighting , LED lamp , and Thermal management of high-power LEDs High-power LEDs (HP-LEDs) or high-output LEDs (HO-LEDs) can be driven at currents from hundreds of mA to more than an ampere, compared with the tens of mA for other LEDs.
Waterproofing is usually required by building codes for structures that are built at or below ground level. Waterproofing and drainage considerations are especially important in cases where ground water is likely to build up in the soil or where there is a high water table.
ATS officers-in-training crew a 90 cm searchlight in Western Command, 1944. A searchlight (or spotlight) is an apparatus that combines an extremely bright source (traditionally a carbon arc lamp) with a mirrored parabolic reflector to project a powerful beam of light of approximately parallel rays in a particular direction.
Single skin with flysheet: A waterproof flysheet or rain fly is suspended over and clear of the roof of the tent; it often overlaps the tent roof slightly, but does not extend down the sides or ends of the tent. Double skin (USA: double wall): The outer tent is a waterproof layer which extends down to the ground all round. One or more 'inner ...
If Q 1 and Q 2 are matched, that is, have substantially the same device properties, and if the mirror output voltage is chosen so the collector-base voltage of Q 2 is also zero, then the V BE-value set by Q 1 results in an emitter current in the matched Q 2 that is the same as the emitter current in Q 1 [citation needed].
Rather, the skin dries and shrinks away from the bases of hairs and nails, giving the appearance of growth. [405] Shaving does not cause terminal hair to grow back thicker or darker. This belief is thought to be due to the fact that hair that has never been cut has a tapered end, so after cutting, the base of the hair is blunt and appears ...
