LED Candles from Hampton Bay

Price: $30 at Home Depot Recommended: for certain applications Also Available: LED candles from many makers are Being available
Lamps are a popular form of accent lighting, especially around the holidays. Recently LED candles have appeared on the market, or more precisely, LED accent lamps in the form of a candle. Designs vary somewhat, but most of the available models use , and electronics that flicker the LED gently to simulate a flame.

The rechargeable LED candle set under review is from Hampton Bay, one of Home Depots house brands for lighting products. You may find this set elsewhere under a different label, but the Hampton Bay mark is a Home Depot brand. the set retails for just under 30 dollars, and includes a charging base and three polyethylene candles that contain an LED assembly. The LED assembly consists of magnetically-coupled charge circuit, plus two 1.2V NiMH batteries and an LED with the electronics to make it flicker. Electrical connectors on the candles, which makes them usable as outdoor lighting even in wet conditions. The charge stand uses a transformer to connect to the mains and must remain indoors.

Set of three candles
Since the candles are sealed, there are no switches exposed either. but you can switch each candle on or off by lightly tapping it on the table top. A switch sealed inside the unit toggles it on or off this way. The candles will also light When removed from the charger, or when power to the charge stand is removed.

Each light body is created by a candle that has been burned. Metal rod (nice in case someone tries to light oneit wont burn). All three candles in my set appeared to be made from the same mold. Each candle is a cylinder 4-3/4′′ tall with 2-1/4′′ diameter The is somewhat smaller than a typical 3′′ scale pillar candle. The sides and the candles are fplus the drop across the current programming resistor.

The singer of the singular .






An example of that would be driving four white Star/O LEDs, the cumulative forward voltage is 4* 3.65V = 14.6V. Add 3V for the driver, and the minimum supply voltage is 17.6V. Also note that the LM317T is capable of Accepting a supply voltage up to 35V, so this driver circuit could run up to eight Luxeon Stars in series.

If you shop around, the parts to build this should cost less than a dollar, but you can definitely build it for less than two. This design is superior to the use of a current-limiting resistor with a regulated voltage supply, since less power Is dissipated in the resistor for most cases, and more importantly this can be used with a relatively poorly-regulated input voltage without harming the expensive Luxeon Star.
