Going green requires more objective inspections and this nice gadget will help determine energy savings by identifying over-lit areas around the home and work areas. It is a well-designed unit and looks and feels robust to serve you several years. It also has an orange rubber housing to cushion knocks (and possibly falls from a moderate height). The measurement display and buttons are nicely laid out and clearly marked; once you familiarise yourself with an accompanying brief user manual, I don''t think you''ll need to consult the manual again. It is that simple to use. The light sensor comes as an attachment -- with a coiled cable as connector to the main unit and a protective cover for the light sensor -- which means you can easily pin-point measurement areas at ease (say, to measure precise lighting in food preparation area in a kitchen, or typing area in an office) while the main display unit can be held with the other hand or positioned stationary nearby. For average home use, this is one of those gadgets with very minimal ''use rate'' - i.e., once you completed your energy savings project with this gadget''s measurements, chances are it will be boxed away for quite a while until its next use. (Well, you can always tell friends and relatives to borrow it thereby maximising its value-for-money. Also, well suited to school science projects, so at times may be used to keep children scientifically busy. Just some examples to widen the scope of use for this gadget, and with its robust construction (no moving parts other than the attachment) it''s a type of instrument that doesn''t cause undue concern even if loaned to others who are capable of using it with basic care). The instruction manual for first time use is very poor indeed. The one thing that should always be clear at the outset for an instrument of this type (or any type for that matter) is how the user should go about putting the unit into operation (and without any guesswork!). You go through a 7-page Instruction Manual (about the size of UK passport book) and there is nothing to advise how you put the unit into operation. You come across on page 5 under "Battery Check-Up & Replacement" to tell you how to open the battery compartment and even that is wrong. You read "... press the cover and push in the direction of the arrow to open". There is no arrow on the cover. There are two spare screws enclosed in the box and the instruction doesn''t tell you what the screws are for. Yes, easy to figure out eventually, but bad practice not to mention it. The screws are for securing the battery cover to the unit; you only need one but good to have a second one as a spare. Once you slide down and open the battery compartment, you''ll find a 9V battery wrapped in polythene film, which of course you need to unwarp and connect to the battery terminals. Before all this, you need to remove the main unit from the orange rubber housing. The orange rubber housing is a nice snug-fit and you could actually mistake for a glued-on plastic housing (like handsets), in which case you may be wondering how to remove that battery cover in the first place! All this uncertainty could have been avoided with a simple guide at the outset in the instruction manual, by mentioning everything I mentioned so far in a logical order (which are all missing!). And for this reason alone, I decided to knock off one star, which otherwise the instrument is worthy of a 5-star rating. For enthusiasts (whose hobby it''s to measure almost any physical data), and those whose interest or work is somehow connected with what this gadget does, the price for such quality instrument is really good. Even for one-off use, say for energy saving project around the home, it is quite possible that the cost of this lux meter may be recouped in a few years'' time. For a simple illustration of this point, read my review of Eterna LA03041 D130 28W Fluorescent Super-Slim Circular Ceiling, where you''ll find an example of savings you can make with low energy lighting. This lux meter is vital in avoiding (at least minimising) over-lit areas and hence reduce wasted energy, thereby saving you money.
