The American Trade Association will launch a luminaire labeling program next year that requires a lumen output to allow consumers to effectively compare with other luminaires.
Beginning in mid-2011, the US Federal Trade Association requires all bulbs to have new packaging labels, making it easy for consumers to choose different bulbs on the market.
In November 2009, the trade association proposed to indicate the lumen output rate on the light bulb, and said that the new measures will take effect within about one year from then.
Congress urged a re-examination of existing labels, and the Federal Trade Association designed new bulb packaging labels designed to allow consumers to choose the most efficient fixtures that best fit their lighting needs.
For the first time, the label on the front of the package should focus on the brightness of the luminaire in lumens (see note) instead of the wattage measurement. The Federal Trade Commission said: "Explaining the brightness of the lights with lumens can help consumers make decisions and buy the most economical and energy-efficient bulbs."
The new label front also indicates the estimated electricity usage of a particular bulb for one year.
Moreover, there is a nutritional ratio map in the similar food package on the back of the label:
Brightness Energy consumption Lamp life The color temperature of the lamp (eg whether the lamp is warm or cold)
Wattage, is there mercury?
The brightness of the bulb calculated with lumens, indicating whether lead is also printed on the bulb. The labeling requirements shall take effect one year from the date of promulgation. The Federal Trade Commission also seeks public comment on a number of issues to further improve the labeling requirements for light bulbs, such as whether new labeling requirements apply to wax table bulbs.
Note:
Lumens are luminous flux units (the total amount of effective light output), and brightness or luminosity is the luminous intensity per unit of luminous area, calculated as how many candela or nit per square meter.

Why do Lithium batteries last longer than Lead-acid?
The nature of Lithium and the integrated Battery Management System (BMS), allow Lithium batteries to last five times longer than Lead-acid.
If you opened the casing (which we definitely don't recommend!), you would see that a Lithium battery consists of a number of individual power cells which are joined together to offer the required capacity (number of holes you can play). The Battery Management system is a really clever piece of kit (think of it as a mini computer), which performs a vital role in keeping the battery components safe, while allowing each power cell to discharge at an even rate. This system spreads the 'load' on the cells and reduces cell damage to maintain capacity for as long as possible.
Can I top-up my battery between rounds?
Another benefit of Lithium batteries is that they can take a 'top-up' charge. What does this mean? In practical terms, it means that it does not need a full charging cycle to 'top-up' the capacity (number of holes you can play). A common scenario would be a golfer who is playing 36 holes in a single day and decides to put their battery on charge between rounds. The capacity will be topped up for as long as the battery is on charge, which might come in VERY handy after a long and tiring day out on the links! This is very different from a traditional Lead-acid battery, which is only worth charging for a full cycle - that's a minimum of eight hours! In addition to this, a Lithium battery takes a speedy 4-5 hours to fully charge from empty - that's got to be good for your electricity bill!
Should I leave my battery on charge all the time?
No is the simple answer, because you really don't need to and it is always safer (plus greener) to leave appliances unplugged if possible!
Don't worry though - your Lithium battery and its dedicated charger are designed to 'switch off' once fully-charged to reduce the risk of continual charging and the potential for overheating. We therefore recommend waiting for the charger light to change from red to green, before switching off at the wall and unplugging the battery from the charger. This doesn't damage the battery and the battery will hold its charge until you next play.
