In an ideal world I would want the original ARB ones http://www.arb.com.au/products/vehicle-lig...ed-lights/ but they are so expensive @ almost £500 each so am considering a compromise http://www.ebay.co.uk/itm/9inch-225W-Cree-...5d5d41ff6e
The interweb feedback on the grey products have been positive (from what I have read) so am wondering if any of you have fitted these to their pride and joy? |

Well at least the IP rating seems good.
Before you get too excited about the price just remember that you might get stung by Paypal/bank charges and the exchange rate also
HMRC, Royal Mail/Parcel Force etc work together. You are liable for import duty probably around 8-10%, plus VAT plus a handling charge depending on which courier handles it of between £15-£30 There again they may slip under the HMRC radar. More details can be found HERE Brendan |

See here http://www.defender2.net/forum/topic41496.html
I've just fitted the 9" Cibie Super Oscar LED's and they are amazing, quick pics on the post above don't do them justice. Cost for the pair was less than one of those ARB's. I opted for the black wide beam without position lights. 1200 lumens with 500m range for the ones i have. Going to try to get a bit of GoPro footage tomorrow night to show them off better. |

Thanks guys.
The equivalent 96 watt (as per ARB) is only £73/light http://www.ebay.co.uk/itm/Red-Round-9Inch-...5d50d50467 so even if HMRC fleeced me 100% of the cost I am still potentially £300 better off per light 
Flyingfocrs, thanks for that direction to another brand 
Mmmm, decision time  |

They seem to be good from what I can see.
Brendan - I know it's extremely difficult to tell but would you say these above at 7200 lumens approx would be brighter than 100w Roolites / LF equivalent. Any idea roughly? (I have a pair on 100w Roo's myself. |

Hi Steve, a very interesting question however as you say very difficult to answer.
First the human eye/brain can not readily cope/calculate the total light output from a projected light source. Personally I would like to see all lights in the 4x4 market marketed with a scientifically measured light output to a set international standard. Combine this with information such as IP rating etc which is measured to a known standard then the end consumer can make an informed decision about their purchases. It makes me shake my head with disbelief when I see comments such as 'these lights are waterproof as I have dunked them in a bucket of water' Light technology has changed dramatically over the last 2-3 decades. Light sources have changed from filament bulbs (maybe in different gases) HID, LED and now laser sourced lights. Historically lights have been classed by Watts, however this is a measure of electrical power consumed and is not a measure of light output which is know as lumens. To change light output you could change the filament diameter, filament material, temperature of filament, gas in the bulb etc. So as the wattage got higher the brighter the light. Fast forward to LED's. The light output from these were initially very low and with time improved so how do you compare these new lights with traditional lights? The good old Watt! This is a useful unit as you can say you get the same light output for the same power consumed. Now LEDs are classified by lumens. Raw lumens is a theoretical calculation of what the light output is and assumes everything is working 100% perfectly. This is the headline figure and what manufacturers like to use as the number is highest. Then you have effective lumens, another calculation where from the calculated raw lumens have assumed losses subtracted from it. This figure is a lower figure and can be up to 30-50% lower then the raw lumen figure. If only one figure is given then it will most likely be the raw lumen figure as that is the higher figure. The figure I personally would prefer to see is a scientifically measured light output in lumens. The main LED manufactures grade their LED output with the best light output commanding the highest prices. The ones with poor light output are obviously the cheaper ones with a range of performance and prices. I will let you decide if you think the cheap LED light bars are made from the best quality LED or the lower grade ones. Now improvements in LED's have given rise to larger Lumen output over the years. Typical Lumen output is now up to 90-100 lumens per watt. I have heard that the latest LED can have a raw lumen output of up to 200 lumens per watt. Also the size of LEDS have increased from a few watts, Vision X has the 50 watt Canon which has a single 50 watt LED. Have heard that there are now 100-200 watt singe LEDs available. 100 watt Lightforce lights have an output of 382600 candela. Now it is possible to convert candela into lumens if you know the semi angle of the solid cone assuming that is 10 degrees then lumen output is about 10,000 lumens Now Lightforce lights tend to be a lot more 'yellow' then the whiter LED light. So back to your original question would a 100 watt Roolite be brighter then 7200 lumen light bar? Now is that raw lumens, effective lumen or measured lumens.. On paper the Roolite would be brighter, however would it appear brighter to the average human eye due to the wavelength of light differences between the two light sources. So a difficult question without a simple clear yes or no answer. Hope you understand my long winded waffle/discussion and reasoning! Now you might understand why with light output I would like to see all light manufacturers using a standard set of specifications. Brendan |

If OP intends to use them and install them as driving lights, don't they have to be E-marked here?
I vaguely remember that these ARB lights were discussed here a while ago, and that lack of E-marking, I believe even lack of DOT marking, make them only legal for strict off road use everywhere. Interesting statement in the cheaper Chinese ebay copy offer too: ""No need to buy euro lights any more, just use our diffussion covers to convert the beam pattern"" Yeah, right. 
Eric You never actually own a Defender.

Eric, diffusers work a treat converting beam patters! Several manufacturers including Roo and Lightforce sell them too! Available in spot, combo or wide beam patterns.

Picking up a bit of what Brendan is saying about standards across manufacturers, the silly thing is that in the closely related field of torches there *are* standards that most reputable manufacturers use to measure the light output, so 100lm for 1hour is the same whether you buy a Fenix, Eagletac, Surefire or Zebralight. There are other variables like beam angles, colour temeratures and CRI but there are at least some industry standards for comparison and measurement.
