Too much light???
« on: November 28, 2021, 04:11:57 PM »
Lots of nice light, but not convinced. Next mockup, next weekend will be to line the fenders under the lips.

Maybe a tidge, try a section on the top of the inner hood by the latch. Try to mask the excess to get a true level. Add some to each side of the center support.

I tried just the bottom light, not enough. Then put the top on, covered the sides. It's a good amount of light. I like the illumination of the ring, but don't like how the sides glare out at you.

I'm worried about their adhesive holding up under the hood with the heat. Have 3M double sided tape, rated to 200F continuous and 300F short term. That should work. I tried rubbing the adhesive off the led, it comes off, but it's slow and leaves a residue. Time to get the goo gone out and experiment...

I'm in a industry that's involved in lighting, especially in high end homes. So I like to geek out on this stuff... ::)

Rule of thumb is 'see the effect, not the source'.

I would make a channel across the top of the hood and aim it broadly at the engine well. You might need brighter LED, and even use a channel that is reflective. Or even a couple of channels... ;D

Add to each side of the center support a couple of rows for brightness and you may have a winner!

BTW, it's a VERY cool idea!

Thanks Johnny,

I had a rough idea, found others who have done it on the internet. So not original, but I really like the light. I've got the magnetic switch to install this weekend too.

My good friend thinks I should only do lights that are held with screws.

I've got some lights for a different purpose that maybe I'll mock up for the top that screw in. I can't figure out how many lumens the string of LEDs are. I like the led in the back. You can really see distributor with those.

These are 6w, these might be okay, 1, 333 lumens.

These are 36w, think fog lights, 10,000 lumens, too bright.

Those are cool lights! They make great headlight enhancers.

Something to keep in mind is that the color temperature (Kelvin) will affect how the actual color of your engine compartment looks.

I know it's strange, but going into the upper range of color temp like 6500K, while bright, will change how the eye sees the beauty of the colors you have created.

Going with a lower color temperature like 2700K to 3500K will keep it in the range of natural light, in which the original color are reflected back to our eyes.

Lower temperature as measured in Kelvin (K) is NOT related to "Brightness" as we perceive it.

The Sun is our reference. It sends down a full spectrum of light in wave lengths of colors that we can see, controlled by the pigment in the surface of our subject, and depending on its properties, resonates the color frequency, reflecting to our eyes the color of that frequency.

So pigments that are in the red spectrum will only ever reflect red. Blue, and every color in between, the same. Pretty good Design, wouldn't you agree?

I warned you, GEEK I am with this stuff... ;D

Thanks for the info Johnny, I always look at lumens for brightness, my wife looks at Kelvin.  I'm not really a color person. This helps explain it.

I decided to go with two rows of led. It's pretty light, but not enough for serious engine work. I like it.

The Kelvin seems to work with the blue and make everything a blue tint.

I hope you don't mind if I lift this idea for the '80 C10 I have under constructions. I'm going to look for  channel to put the strip lights in though.

It's a really nice touch, haven't seen anyone do this before!

Not at all. Copying is the best compliment! :-)

Looking forward to see what you find. My friend kept telling me to find strip lights instead.

Yeah, this thread has inspired me to find something to put under the hood for those inevitable night time roadside issues. I seriously doubt it will be as elegant as what is featured here, but Pearl was never intended to be just a pretty gurl. More a stout, practical, but cute one. Ok, maybe a 2" lowering but it's all about the payload for this one.  :D

I tried out my magnetic switch, it runs on when I close the hood and off when I open it. Sigh. Time for "normally closed" switch.

Argh, don't use those leds, mine shorted out, they aren't sticking properly to the 3m Tape, going to have to take down.

The new switch works, though.
