200,000 Lux Light Meter

This Light Meter is perfect for our requirements - we are comparing the light output of our LED products to that of other lighting types such as fluorescent, discharge or halogen lighting and this easy-to-use meter is very fit for purpose. We ordered 2pcs of the Light Meter LX1330B from ChargerBuy. The whole process was straightforward, efficient and painless and the products arrived on time and in full. We commend ChargerBuy for their service and can recommend them without hesitation.

Great value and accurate

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.

It definitely works - I tested it out with a different device simultaneously. It's great for checking the lux in those tricky spots without getting blinded by the light.

I bought this and ended up rearranging my entire plant collection! It's a really handy tool to ensure your plants are getting sufficient light.

Reasonable price, accurate and easy to use.

I've had this for a couple of years. I had to return the first one straight away because there was an intermittent fault (the reading would drop to zero from time to time) -- I suspect a broken wire to the probe. The replacement has worked fine though it has one minor irritation: it draws about 16 microamps from the battery even when turned off, which is enough to drain a PP3 in a couple of years. Not an issue if the meter is in regular use, but if you just get it out of the cupboard once in a blue moon to check something, it's irritating to find it's stopped working!

All as advertised, very reliable and quick delivery!

Working properly, I get reasonable readings for the light intensity.

Utile pour mesurer l'éclairage dans les parties communes d'un immeuble ,où des normes d'intensité lumineuses doivent être respectées en fonction de dispositions légales. Instrument utile pour Syndic d'immeuble. J'ai regretté que le mode d'emploi n'explique pas comment mettre les piles: j'ai mis tout un temps avant de comprendre qu'il fallait au préalable retirer la protection périphérique en caoutchouc orange et seulement ensuite dévisser le couvercle du compartiment piles, en partie inférieure du dos de l'appareil.

Practical, easy handling, accurate

perfect for adjusting lighting distance, works on all light types, just be aware that it only measures visible light!!! it doesn't measure light humans can't see (PAR values with UV and IR) most LEDs have IR & UV also so they would not be included in the lux amount the plant actually gets, but still quite useful (would just be a little more lux IE: if aiming for 75k lux. maybe set your LED setup at 65-70k on the meter just to be safe

good product
