DIY modification HQI to LED

[juliovideo]

A nice project I did ,calculating the space it all a compact package, I'll put the details in comments and photos.

Materials for a lamp.

Cables - 20 Ga. Silver Plated Teflon Wire (Mil-W-16878) with specifications for military and aerospace. 20 Ga. Silver Plated Teflon Wire

Screws, nuts, washers and pressure ...... all of stainless steel and replacing the lamp that are 7 of 8/32.

A Mean Well LPC-60-1050 constant current driver.
Two Mean Well LPC-35-700 constant current driver.

A Heat Sink Drilled / tapped 6 "x 9"

Masscool - Thermal Gel for LEDs

Two 92mm Vantec Stealth Fan Kit with a speed control.

Extension cord to connect the fans

24 LEDs of 3 watts .... tin were welded with a 5% silver composition.

Rapid LEDThe lamp to change is the Sunlight Supply Lumen Max 3 250W Double Ended HQI Reflector.

In this first picture had already removed the socket and bulb.

In the next photo I had to cut the 6 brackets that supported lamp sockets and reflector.

love it!

More pics please...especially if you have any before and after would be nice. Also...par readings would be great my friend.

How are you controlling these for sunrise and sunset?

Thanks Frank :smile: ,I have for the sunrise and sunset 20 leds of 1 watt ...............

 

[bige]

Well done. Looks great.

Thanks Frank :smile: ,I have for the sunrise and sunset 20 leds of 1 watt ...............

Oh...the good old powerbrites..too bad they don't make these anymore.

Julio post a full tank shot with the new led setup please.

Very clean setup. Nice work. Are you happy with the color output? What would you do different?

Thanks ! ; I am very pleased, especially with the growth of corals.

The Japanese have made their own board of this issue of the LED, I show

The photo on the left represents the solar spectrum, and the photo on the right gives an idea that within the solar spectrum (color LEDs), gives the color pigments in corals ....... represented by curved lines within of the graph.If you look to take one example ......... if there is a lack of red in the coral is the absence of cyan.

We see interesting things, green and yellow is present almost in the extreme, one in the red zone and another in the area of ​​blue and royal blue ;Here you can choose which area we like to see light as the aquarium, the only color outside the range is nice to see the aquarium would be the blue pigment,but I think with the neutral white LED covers that area.

I would like to talk about the UV LED, have asked me via PM the difference with the Royal Blue.
[FONT=arial, sans-serif]
[/FONT]The ultraviolet energy is classified into three categories. (sorry if there is any misspelling, my english is not so good )
[FONT=arial, sans-serif]
[/FONT]UV-A radiation is just below the violet portion of the visible spectrum and consists of those wavelengths between 320 and 400 nanometers (nm). UV-A is invisible to the naked eye and is the least destructive.


Wavelength UV-B (280 - 320 nm) are biologically destructive and, through excessive exposure causes erythema (sunburn).


The third category comprises UV wavelengths between 200 and 280 nm and is known as UV-C radiation. Earth's atmosphere absorbs UV-C radiation from the sun and thus are not found naturally. However, UV-C can be produced by artificial means. Arc welding produces UV-C, so do the electric lamps in certain specialties, such as those employed by the fans for the sterilization of aquarium water).

Then we care about is the debate between UVA and UVB.

===============

The 3W LED UV Violet selling and 410nm to 420nm is between is in or near the edge where it starts the UV-A ........ because the UV-A range from 400nm to 320nm right? , .... then we should not worry.


This chart shows the royal blue, violet and UV rays to the left.

According liveaquaria comment ........."It's not uncommon to see These colorful corals to Adapt to the Lowest Conditions of UV-A and UV-B found in home aquariums. The loss of pigmentation is Not Necessarily a sign of a healthy coral - is just a normal coral adaptation to Their new environment. "

The research work that have made private aquarists all seem to come to the conclusion that the coloration of corals appears to be directly related to the exposure of some UV rays and is a genetic mutation that helps protect your developing a transparent mucous algae for apoyo.Tambien protection as the shallow colrales have a more intense color than those that are more profound.

Aquarium-Design said in an article ......[FONT=verdana, geneva, lucida, 'lucida grande', arial, helvetica, sans-serif] [/FONT]"Perhaps the best source of information on this subject was published in 1995. Titled "Ultraviolet radiation and coral reefs," this book contains many articles on the effects of UV radiation on corals, zooxanthellae, plankton, etc. Clearly, these present a convincing argument that ultraviolet radiation can have a major impact on coral reefs in many different ways."

Julio my friend, how you doing? Julio is a DIY guru. He does some incredible stuff that looks professionaly done. That is one nice LED fixture you made. Please post up more pictures.
