Milwaukee Electric Tool Corporation has introduced a new LED Upgrade Kit that can replace 9.6-volt to 28-volt incandescent bulbs in both Milwaukee’s and other manufacturers’ worklights. The LED Upgrade includes an aluminum case that dissipates heat for cooler running temperatures and a 50,000 hour solid state light-emitting diode that promises to deliver over 250 times the life of incandescent bulbs. The LED Upgrade Kit (49-81-0090) sells for $29.
