Recently we received an inquiry from a customer asking us “How is one able to compare Lumens, Wattage and actual usable light?”
They went on to say:
“I have seen a 5 watt LED that claimed it was equal to a 60 watt incandescent; whereas it was visually as bright as a 10 watt light bulb. Yet I have seen floodlights (2 bulbs) rated at 1190 lumen’s 240 volts & they appeared twice as bright as the two 100 watt light bulbs.”
We can understand the issue with regards to the confusing comparisons in the LED Lighting field that many a consumer is faced with and so with the above questions in mind here is what you need to know.
One of the first things to take note of is that the cheap and imported LED lights, like many of those found on the web, are not rated anywhere near the actual LUMENS output that they state, unless you know what you are looking at you can get caught out with inferior LED’s.
The second thing to keep in mind is the actual chipset that the LED is based on. If you want something that actually states the LUMENS output correctly then you need to be looking for LED’s that have either, and original Epistar or a CREE US based chipset. These are the types of HIGH Quality LED’s that we supply at ACDC LED Lights. Not CREE copy coming out of China.
You will also need to take into consideration the angle that the LED emits in MR16 & GU10 Down lights at, 20, 30,45, 60 degree etc. along with the colour that the LED produces like white, cool white, warm white etc. All of these will have an effect on how bright and how far the light will travel.
Down lights should be no more than 2m apart for LED replacements or you might have a show effect between the light output.
For a guide on colour and brightness you may want to read over one of our previous articles, although it does not cover everything explained above it does contain a LUMENS chart that will show you what amount of LUMENS will produce the light you are looking for. Any good LED supplier, like us, will be able to produce information and evidence of the LUMENS a particular LED will produce.
When it comes to WATTAGE what you are looking at is the amount of WATTs per hour that each LED will consume. This is much the same as any other light bulb be it LED, Incandescent or halogen.
When it comes to VOLTS on an LED you will find that this is the rated voltage system that the LED can be used in, e.g. 12, 24, 240. So as an example an LED rated between 110v and 240v will work in a standard home light socket within Australia.
In response to the above our customer responded with the following:
You are correct about the LED market. I purchased a 5 watt Par 20 cool white LED flood light (with between 30 & 50 led’s covered by a glass lens) from eBay. In complete darkness it would not even cast a shadow if you held your hand 6″ from the face of the bulb. Yet a Phillips cool light at .072 watts illuminates better than twice as well. Then I purchased a double lamp CREE LED floodlight rated at 1100 lumen’s total, cool white and it was much brighter than the 2 lamp halogen with two 100 watt Par 38 bulbs.
Maybe it is the difference between the cool white LED VS warm white of the Para 38 bulbs but they were GE or Sylvania so one would think they are reputable.
Thank you for your help.
So there you go, now you should know what to look for in an LED Light as you make your way through your home, business, car, caravan etc. replacing your high cost energy bulbs for more sustainable and cheaper to run LED Lights.
