Why choose Lumatek? • Lumatek ballasts include a 15 foot RF shielded output cord that can be extended up to 30 feet. (Allows positioning of ballasts in another room or at great distance from your space.). All other digital ballasts can only have a 10 foot lamp cord and most of them interfere with radio and satellite TV signals because they are not shielded. • There are no fans to break down or make noise; fan cooled ballasts have a very high failure rate. Lumatek ballasts are very reliable, which is why we offer the excellent warranty. • The ballast can be mounted in areas of high heat, up to 140° Farenheit. • Every Lumatek ballast is burned for 12 hours at the factory • Excellent three year, full exchange warranty • Lumatek ballasts are 8% brighter than ROM and future ballasts • No fans to break down after 1 or 2 years • Safer - The Lumatek ballast is completely sealed from the inside
