Inexpensive LED auxiliary lights 12/24VDC - 7 watt $30
Posted: Mon Dec 10, 2012 11:44 pm
I ordered a pair of the BlitzPro - 6LZ LED COMPACT LIGHT BAR for $30 each - and I am impressed. Nice quality construction and bright even pattern (with no "cut-off" line). Very low profile and small - only 6 inches long by 2 inches high. Super fast delivery too.

BUT - there is something fishy going on here. I put them on my bench power supply and dialed them up to 14.0 VDC - and they each used about 0.45 amps. That's right around 7 watts of power - which is impressive for the amount of light produced - far from the advertised consumption listed at 18 watts.
I suspect that these actually use six 1 watts LEDs instead of six 3 watts LEDs as claimed. This would also match better with the price they are selling these for - 3 watt LEDs are not cheap and are in demand for a wide variety of products while 1 watt LEDs are much cheaper and available from more vendors.
They also only claim 800 lumens of light output for these 6LZ compared to their Hawk 6D light which they also sell and list as using six 3 watt LEDs / 18 watts and producing 1355 lumens or their 4LR light which has four 3 watt LEDs and is listed as using 12 watts while producing 900 lumens.
So - I am not saying that I am unhappy with them - in fact, for what I want them for (camping lights and backup) they are better matched to what I needed/wanted - Just want to make sure people get the "real" specifications and not just some hype. It would be good for BlitzPro to fix their website too.
Also - I am not sure I would use them on the front for fog lights as I think the lack of a cut-off line would cause to much glare to other drivers and, if aimed down at an angle to reduce glare - would illuminate the area immediately in front of the vehicle too much (often called "hot spotting) which could reduce the ability to see well at night.
Its also interesting that Google Chrome's tab at the top of my screen actually calls these lights "Roof Rack Lighting" as that is exactly what I intend to use them for...
