fiber optic cost

[Anonymous]

hi.
I would like to find out the cost of the fiber optic cables used in the discussion...

Did you look into the use of filter (hot mirror and blue filter, e.g.) between the bulb and the cable? Maybe able to use a lower Kelvin bulb and decrease the heat build up...

Here's a site:

150 Watt metal halide $699.00. Color or twinkle wheels are available for an additional fee.


It might be worth it to get the "twinkle wheel" What I don't get is why do you have to buy a kit? This doesn't look like much more than a reflective pendant. You take that, put a board on the end, drill a hole, insert fiber strands. Am I missing something here? (Other than the bulbs for lcd projectors that cost $200-500 put out more light)

A few others:

This one looks promising, a 400W 5600K MH bulb, no price: :?:

A blue filter can be used to raise the color temperature of a light source provided that there is enough short wavelength light intensity to make it worthwhile. A blue filter will make an incadescent bulb look blue, but little energy remains after you've filtered out all but blue wavelength light.

Quartz halogen bulbs (the other option with fiber optic systems) produce very little short wavelength light, so it wouldn't really be worthwhile to try to raise the color temperature. That's the significance of the metal halide option; The color temperature is high enough that filtering isn't necessary.

hi.

An old aquarium frontier article titled "A Poor Man's 10,000 K Bulb" by someone you very familiar with is what prompted me to give you the suggestion you are no doubt aware of. What I want to know, but surprised by your answer is that the use of a cheaper bulb may be a good idea with filtering in this setup.

Did you mean to write "may be not a good idea"? If the hobby develops a way to use something like an Iwasaki as a fiber-optic light source, then filtering is an option. Most other cheaper options just aren't going to be very useful.

My point in writing "Poor man's 10K" was that if a hobbyist wants a tank that looks blue, using a high color temperature bulb is not the only option and depending what we're comparing, may not be the best solution. On the other hand, a shallow natural reef isn't very blue, so a blue tank isn't necessary.

Yes, sorry about the carelessness.
