Ridiculouser...
As some of you know I have been keeping an off-and on lookout for the macabre in LED light bars and this is the latest patient... At some time hopefully in the near future The People's Repu...

Told D'ja it is macabre. Meant to bring a smile. Being that I work intensively with LED's and power supplies, I can remark that a 300 watt version of this bar cannot be compared to an 18 watt lamp. Oh poor Mex. He actually MEASURES these devices.
The 18 watt versions of CREE lamps regardless of design draw 1.04 amperes at 12.00 vdc. My 300 watt light bar drew 15.65 amperes at 12.00 vdc.
If a genuine CREE chip 18 watt lamp is compared to a 6054 old style rectangular headlight bulb. A genuine shootout - the 18 watt CREE wins - by a landslide. Four mechanics and a dozen people watched. BUT WAIT! The power supply voltage was increased to 14.0 volts for the 6054 lamp. Still it was a laugh-off. 16 people were shaking their head. That 1.04 amp CREE (Other brand chips are a joke) lamp is a marvel. It has a voltage regulator inside 9.8 volts to 29.95 volts it puts out the same light EXACTLY. It's a pure E=I/R METER READING proofing.
So when you install your "X" watt advertised incandescent bulb replacements in your rig 1-2 watts is all the heat that can be squeezed onto a SMD PCB. Test latest CREE beta chips I tested STILL need heat sinks far in excess of what any lamp cutout cavity would provide.
My new 3rd brake light (8) 160,000 mcd red 10mm LEDs in the back window passing through a narrow plastic strip diffuser made all the difference in reducing tail gating drivers. Even though my CREE replacement headlight bulb replacements are considered by me to be another wonder of the world, I'm still looking forward to mounting a pair of NARROW BEAM 18-watt CREE lamps to shine 50' forward and down toward the curb/shoulder.
MORE CHATTER: My one thousand five hundred watt monster lamp has been lighting up the futbol pitch at home for almost a year. I balanced load to rectified transformer potential at 140 volts max. Wuuwuu a 10 watt 130 volt zener diode interrupts a relay coil. Wotta hoot.
I sold perhaps 30 CREE light bars. I refused orders in excess of 300 watts. These bars save lives in an extremely unusual circumstance where "going to town" means a 150 mile drive, and seeing perhaps ten cars, but a few dozen asphalt tinted cattle on the asphalt*. I will not sell bars here in the new place.
* Oops! Sorry. I sold the light bars in NORTH AMERICA. Proper use of a potentially hazardous product means THINKING is mandatory. Perhaps beyond the ability of too many folks. But for anything but the most rural untraveled back roads laden with cattle, washouts, or deer having a potent light bar is silly.
Just as silly as getting a five hundred dollar ticket for blinding someone. Strike silly, replace with two words stupidly-arrogant.
