Figure 1 Predatory and HI (host-or prey-independent) life cycles of Bdellovibrio bacteriovorus. The small, motile, monoflagellate, attack-phase bdellovibrios do not divide, except by replication within the periplasm of a gram-negative prey bacterium.
F. Remove the old battery(ies) and replace with the new battery(ies). If your solar spot light has more than 1 or 2 LED lights it will more than likely have more then 1 or 2 batteries in it. Inside the battery holder it will show you how to place the battery.
LEDs come in many colors, and some LEDs contain multiple elements and are therefore capable of multiple colors. LEDs are most commonly used for keypad backlights and service/message indicator lights. LEDs are also often used for LCD display backlights. Bright white LEDs can provide a flashlight function. Recently, bright white LEDs have also been used to provide a flash function for a camera-phone. An LED camera flash is generally not as bright as the xenon technology used in standalone cameras. Some LED flashes are brighter than others, however (up to 20 times brighter, in some cases.). LED flashes remain lit for a period of time, unlike the extremely brief strobe of light produced by xenon technology.
