LED BULBS CONSUME 3 W FOR 12 VAC/DC & 24 VDC SYSTEMS |
|
 LEDtronics has added to its line of drop-in replacement MR16-styled LED bulbs: 3 W LED MR16 bulbs. The 3 W MR16 LED bulbs are said to have two advantages over other MR16 LED bulbs. First, they are engineered to handle the variations in voltages that may accompany “noisy” or “dirty” ac or dc power supplies, eliminating potential burnout from incoming voltage that is higher than the lamp’s capacity.

FLUORESCING TECHNOLOGY FOR INSPECTION |
|
 Dymax Corp. has introduced Ultra-Red fluorescing adhesives that remain naturally clear until exposed to UV light, at which point they fluoresce bright red providing a vivid contrast that permits accurate bond-line inspection. The red fluorescence does not absorb the same light energy wavelengths as those used to cure the adhesive, resulting in faster and deeper cures when compared with the same adhesives containing blue fluorescence, the company says.
