LED technology!

[Aarzoo]

Theres future for cooler light ???? Maybe expert here can comment for DIYer

Features
• Very low heat generation
• No ballast required
• No reflectors
• Targeted light output
• High shock/vibration resistance
• One year warranty
• Typical LED lifetime of 100,000 hours
• Power consumption less than 6 Watts as compared to 100 to 1,000 Watts conventional grow lights consume. On average, you use 33-times less energy with our LED-PLANTBARs
• Lower voltage (after passing through power supply
• Lower burn and fire risk

I've looked at this technology for some time. Although LEDs may be able to emit light at the right wavelengths for plant growth, I doubt whether the lumens are intense enough. At this point, I am guessing sufficient lumens at right wavelength is crucial for plant growth and I am also speculating that LEDs won't be able to meet. If you have some data for LEDs that may help to analyse the feasibility of it.

However, if you are just looking at LEDs as a source for illumination, I think this is a very viable option.

And also to add that for flower and fruit cultivation, the lighting is not meant for "admiration" unlike for planted tanks and aquariums. We want to enjoy bright daylight viewing whereas those out of water plants are usually under blue/red lights. Also not sure whether LEDs light is strong enough to penetrate through water to reach the plants.

Hi,

Those interested in LED technology for planted tank might want to check out

A member there, Gomer, did a set up with some comparison of LED vs PC lights on plant growth.

Check here too they already have for reef aquarium

PFO Lighting is proud to introduce the Solaris LED Illumination System. The Solaris is the first LED System designed to replace Metal Halide and Fluorescent lighting for the Aquarium Reef Tanks. It has been in development for over two years. It will change the way Aquarists light their tanks from now and into the future.

The current design produces PAR light output levels equal to a 250W MH 20K. It uses 40% less energy than the Metal Halide Fixtures it replaces. The life of the LED's is 50,000 hours, so it almost eliminates metal halide and fluorescent bulb replacements. All heat is radiated up and away from the tank Therefore, it does not heat the water like Metal Halides or Fluorescents. This eliminates the need for Chillers. The room air conditioner needs to work 1/2 as much since the light fixture produces only half the heat of Metal Halides which saves even more energy over traditional lighting methods.

There is a built in microprocessor that controls the Solaris. This not only eliminates timers, but it allows the unit to dim the actinic blue LEDs, white LEDs, Lunar actinic blue LEDs and Lunar White LEDS independently from 0-100%. This dimming capability opens many opportunities. The light can be adjusted from 6.5K to 22K, or anywhere in between, to set the ideal color temperature. Sunrise, Daylight, Cloud Cover, Sunset, and the lunar cycle, can all be set independently.

Coral Growth has been outstanding with the new lights. There is excellent water penetration of the light. Many authors have been testing the units since early May and will be printing their results shortly.

But at what price?

[BFG]

Look at the price. An eye-opener for a brand new technology! I can't afford the 4ft model as much as I want to get it.

Looks like T5 will still be on the table for a few more years.

[Nicky]

Don't worry.. once the technology is on the market, the world's factory China will make it affordable for us soon...

[chanck]

Maybe we can volunteer as beta testers?

[Aarzoo]

Ha ha ha Nick is right there will be cheaper version definitely and China/Taiwan will make it affordable for us like Jebao & Jebo. But the lifespan does last very long 5-10 years plus I actually love the sunrise/sunset mode which could not be done with FL unless one using dimming ballast "overseas order only". Also one might not need chiller if water temp is good.
