Sales Kit from U-Tron
U-Tron have designed using two simple watts meters side-by-side in an enclosure where you can plug in two light bulbs from different manufactures and show your customer the numbers so he or she can tell for themselves which one is consuming less energy. (The newer version of the Watt Meter from U-Tron has two easy E27 sockets on the top of the box so you don't need table lamps. Ordering part number is 6860-200-R2)
And by using the U-Tron LUX meter you can read the illumination values of each light bulb just by measuring the LUX from an equal distance from the light source. We usually hold it 1 foot higher than the light source. The value is only for your reference and just to compare two light bulbs given all the rest of the environment and conditions are constant. (Ordering part number is 6800-S01-S1)
