How do the Minions Web Ultra-bright all purpose LED Spot light bulbs compare to off the shelf incandescent spot bulbs?
You can compare them to the general incandescent bulbs available from what measurements we could find.
Our actual measurements of some 70 and 100 watt Spot lights on hand yielded surprising results - they measured within 10% of what we consider comparable bulbs.
The one piece of information is that no lighting company wants to declare at what distance the lumens are being measured.
This has led me to believe that the "lumens" cited on most incandescent spot light bulbs available are not remotely accurate.
That "information" is posted in a table below our LED data table.
We have provided 5 distances, and lumens stated on the table are at 1 meter distance.
Please use this table to see the measurements we obtained in bulb testing.
Glean from this data what you may.
All bulbs in this table are 110vAC with an E26 Base (Medium Screw-in) and a 14-22° Beam Angle

How was the LED Bulb testing accomplished?
I do not have a highly sophisticated testing rig, a search on the internet puts the only certified LED testing rig at GE.
I used to do software there, wonder if I can go knock on the door and ask to test bulbs!
For the PAR30 and PAR38 bulbs I took a handy dandy extension cord and stake light to the front yard, with a 33 foot tape measure placed the stake so each bulb face would be 25' from the base of my front steps.
The distance from the steps to the front door under my portico (you can see the layout in the 72 & 120 LED bulb pictures) is another 15' for a toal distance of ~40', not accounting for the slight elevation angle.
I then placed a 1 meter/1 yard (flip side) stick at the bulb face and ticked off 1', 1 meter and then measured out to a 6' point, to create the 5 reference points in the table.
Each bulb was then placed in the socket, powered up, and measured with an Model CT-1334A Digital Lux Meter
at the 5 points. I additionally measured for 10 lux drop off along the measuring tape (or further back if need be) for the Throw reading.
Next I would measure off the width of the illumination on the house frontage
to provide the Field Angle and Beam Width @ 40', since it is a known length of 42' ( I was a civil designer and have a complete CAD rendering of my property).
I did a number of spot reads and averaged them out for each bulb in each distance to get a fairy accurate read on the LEDs
Tidbit - My property has 6 streetlights within 250 of the property centerline that produce an ambient 3 lux read at the stake placement. This produces more additional undesired light than most properties experience. The 72 and 120 LED bulb pictures show how the bulbs at a 40' distance overcome the ambient light.
Halogen Bulb Test Results
The local Home Depot ONLY carries Halogen spots and flood for outdoor use.
These are brighter and extremely hot compared to standard filimant incandescents that I have from past displays. I hope to acquire more regular incandescents to test with asap.
All the bulbs tested in this table are warm white and Philips brand.

How was the Halogen Bulb testing accomplished?
To save time I am at my desk with a lamp on the floor.
Each bulb is placed in the lamp and I measure 1' from the face and take a reading, then another reading at 1 meter. I also entered some observations regarding field width or other comments as I thought they may be pertinent.
Since the Halogen light is very very hot in spots I did not bother to average the readings, I went for the highest reading I could obtain and used it for this data.
It is astounding at how erratic the results are, the LEDs were muchg easier to predict by comparison.
Conclusions
People have asked repeatedly for a 1:1 relationship of LED Bulbs to Incandescent.
It just is not possible - LEDs are overall dimmer than Incadescents but in dark environments such as halloween displays and night time holiday yard displays serve the purpose extremly well, as they are.
I recommend this breakdown:
| 120 LED |
100 - 150 watt |
| 70 LED |
70 - 90 watt |
| 50 LED |
45 - 60 watt |
| 36 LED |
30 - 45 watt |
| 18 LED |
15 - 20 watt |
| 12 LED |
5 - 15 watt |
Keep in mind LEDS will be on averge 25% less intense than Incandescents.
Errata
Basic measuring unit:
lumen, which is an energy of 1/683 joules per second, measured at a wavelength of 555 nanometers.
Illumination of a surface by a point source:
lux = lumens per square meter.
^Throw = The distance at which Lux drops below 10.
*We could not accurately access the actual Field Width of the UV bulbs simply due to time constraints - we have provided an estimate based on the beam angle meeting the same criteria of the similar bulbs in each array size.
**For Lumen/SQ. Meter - use the Lux @ 1' measure. |
