This LED COB light panel operates at 30-36VDC at 1 amp, and it’s insanely bright. On a 6" square PC board--a takeout from unused medical equipment--has (3) rows of (5) white COB LEDs. Board is coated, and each LED has a 7/16” plastic bubble over it. There are (6) grommeted 3/16” mounting holes. Has 18”+ black and red leads on opposite sides.
Save on electricians with this dual spotlight motion-sensitive light that runs on (6) "AA" batteries that you supply. The 2-1/4" long spotlights each have a 3W, 120-lumen LEDs (that's pretty bright) and will swivel 325 degrees while they pivot 160 degrees on a 6" x 4" x 2" thick base. Motion sensor is up to 16 feet. Indoor and outdoor use. Also has a pushbutton on/off switch. In black, with mounting hardware.
Our each is a pack of (10) common cathode 5mm dia red/green/blue LEDs. Clear lens, 20mA rated for 100K hour life. 3V supply will work for all. You also get 100 Ohm and 510 Ohm resistors to step down 5 and 12VDC respectively. Luminous intensity is 4,000 mcd.
These LEDs are wired with an in-line diode on one leg so you can run them with either AC or DC. 24 volts works best (do not run them on 120V!) drawing 4mA. You'll get leads between 4" and 9" with quick-disconnect terminals. You pick yellow or red.
These would be take-outs from cell phones, if they had ever gotten into
any. As it is, these LCDs are new, and relative unknowns. One LCD
measures 1-1/2" x 1" x 1/16" thick and has connection pads that run
along one of the long edges. The second LCD is 1-7/8" x 1-1/2" and has
surface-mounted components and sundry IC and jumper sockets. It measures
2-1/8" x 1-5/8" x 5/32" overall. Sorry, no pin-out information
Ceiling fixtures enter the 21st century. These 120VAC, 11W (65W equivalent) LED recessed ceiling lamps measure 5” dia x 2-5/8” deep with a a back that has heat-sink fins. Mounts via a pair of 3” x 1-1/2” clips and has 5” power leads with a 12mm connector and a 7-1/2” ground wire. UL. Retail prices on these are outrageous but these are takeouts and are in very good shape. May require some touch up paint.
