SPOT LIGHTS?? Types and brands??

The human eye needs reds / yellows to work properly. The pupil won't close properly if those colours are missing. So the LED / HID looks very bright, but only because it is glary. The lack of red / yellow also causes colour rendering issues for humans, so it can be hard to distinguish (for example) a grey kangaroo on a grey road.

Halogen lights are actually the closest light source to natural sunlight when it comes to the colour spectrum.

Or so I am told.

I agree with this and it's scientifically documented that blue is the hardest light for the human eye to focus on. This is exactly the problem with the blue tinted lenses on standard Halogen bulbs. While the lens appears blue it's actually just a filter for all the other colors which gives the end result of less light because the others are filtered out. The thing with HID bulbs is yes they produce more blue light than the other colours but they also produce more of the other colours than normal halogen bulbs. Just to use some made up numbers for an example, a HID bulb might produce 150% of blue light but it will still produce 120% of the other colours. This still exceeds Halogen bulbs.

First we had fire for light then we had Incandescent then HID then LED came in beside HID and now we are going Laser lights.

I'm thinking of starting a company selling Fire Lights. I'll burn magnesium as the light source and sell it as more natural light than Halogen because it is actual fire the most natural light source. LOL :ph34r:

Thanks guys, that's very interesting. I guess my subjective experience of an improvement in visibility was as much due to the wide spread so that at least I was getting a fair amount of light into areas where previously there was very little.

As a comparison: First we had CI engines then we had SI engines...
Now CI engines are in the increase for their additional benefits...

Sorry Joel, but your logic on HID is flawed...

The eye reacts poorly to Blue spectrum light, which when it is in excess becomes the dominant.

HID also changes temperature as they age, a byproduct of their design, so the colour rendering today will be different after a few hours and continues to change throughout the life of the bulb.

Put simply, glare is not bright, bright is not glare.
And dipping a pair of HIDs will result in temporary night blindness as the pupils try to adjust.

Filament (Halogen is a gas not a light) is not subject to such delays in readjusting vision.

LED tech is coming along in leaps and bounds, and it will mature in years to come. Laser is around the corner, with controlled illumination removing the requirement to dip for oncoming traffic, however unlikely to be easily built into driving lights as the sensors and electronics to control will take some time to be integrated...

Having said all that - run what you like...

Nemesis owners like light - lots of it... :D

Thanks Tombie. We've had this debate before. You like FyrLyts. I like HID. I'm not repeating history. :D

And you're welcome to like HIDs. Never said you weren't..

I've run all 3 light sources :) pros and cons of each well documented and tested.

Luckily it sounds like you're eyesight hasn't started to degrade yet...

With my eyes, I have a keratoconus and am extremely sensitive to bright light of any source but night is really bad. Take it from me, HID is glare, be it low, high beam, driving lights or anything. LED is not much better. My eye strain with halogen is virtually zero and there's little issues with oncoming Halogen vs the rest.

A man of discernment, obviously Sappers past and present are a cut above the rest.:p
Cibie Super Oscar with 75w HID :)
At least Cibie are prepared to publish their spread patterns rather than just a lot of hyperbole.

Fyrlyt, all hype no substance?
An interesting post, a lot of Frylite skepticism and then a positive report at Post 26

Super Oscars?

I remember when Oscars were THE light to have.

Still being made by Valeo in Belgium, using old fashioned optics, glass & steel.:)
Apart from anything else I think they fit the olde worlds charm of a Defender

I was given an old set recently - in good condition. :). They are going to look great bolted to the front of my RRC. :)
