Why does Ladder Series LQ001 18x3w LED aquarium lighting best for aquarist growth and breeding?
1. Original import chip guarantee that lifespan and PAR, ideal for promoting photosynthesis.
2. Special lenses design, magnify that chip effect, 60 90 120 degree lenses, providing more footprint than Metal halide and Compact Fluorescents.
3. Blue light, it is more important for growth of coral, duckbill fish and shrimp, promote the coral calcium absorption, synthesis of Vitamin D3, make its healthily growing. White light, best for aquatic plants growth, promote photosynthesis of aquatic plants. Other red, green and purple light, protection the health of aquatic organisms, and make the color of them more vivid.
4. High degree of suture and sealing, perfectly isolated from dust and water, in order to protect the LEDS Better, prolong lifespan.
5. Aluminum heat dissipation led aquarium light, lower that temperature, extend that lifespan, reaching that UL standard.
LED Aquarium Lighting Application:
Ideal for all phases of coral, fish, aquatic plants and all aquatic organisms growth and provide ornamental fixture, promote the photosynthesis of coral and aquatic plants and the growth and development of aquatic organisms. In fish tank, large aquarium, aquatic plants and animals breeding workshop, some aquarium organisms museums and more aquarium related sites, you can see its.

Herifi LED Grow Lights and LED Aquarium Lighting Manufacturer
After years of rigorous research and development, herifi develop different series led grow light, including gemstone series led grow light, diamond series grow lamp, explore series led grow lamp, demeter series grow light, aura seires, ladder series LED grow lights. For aquarium led lighting, we also have two series, 400mm 600mm 900mm aura series and 600mm 900mm 1200mm ladder series coral reef/grass plant LED aquarium lighting.
Why are herifi grow led lighting and led plant aquarium light best for plant growth and coral reef?
1. The equipment and materials to produce hydroponics led grow light and marine aquarium led light fixture imported from Taiwan, Japan, Korea and Unites States, such as automatic SMT machine, reflow soldering machine, all kinds of electric test equipment, large integrating sphere and such sorts of production and R&D equipment.
2. Appearance design insist that simple, elegant, reliable durable, grow led ligning and aquarium led lighting quality insist that high quality and constanly improve that product function, like wifi dimmable and intelligent model.
3. LED grow light design is in pursuit of longer lifespan, higher PAR to stimulate plant growh and flowering, strenghten photosynthesis and yields.
4. LED aquarium lighting design try to do IP68 waterproof, as that UL requirement.
5. More choice for customer, no matter appearance deisng and footprint size and function choose, you require, we achieve that.
This is why grower agreeing that herifi led grow light and aquarium led lighting are best for plant growht and flowering, enjoys a high reputation in grow led lampand aquarium led light fields throughout Europe and America etc.

Ouch, the new member got blazed by Fran, but...Fran is right. I've spent many hundreds...ok a few thousand dollars on lights and the lower priced chinese LED's have never performed as well,. By reading this thread I LEARNED and purchased Rapid LED and A51 and they have performed adequately, I still miss the HPS, but in SoCal, electric costs will eat your wallet.

I would never spend any money on a light source with a 3000-5000 hr service life, especially for $1700. I wonder why all these new MH plasma companies are shying away from luxim modules??? price??? bad spd???IDK , it's weird why you wouldn't rather have a 30'000hr light engine instead.

to be fair I did spend money on some zoomed florasun bulbs(t5) which probably have less than a 5000hr life...........never again though, fuck that:P

Good catch PSUAGRO.

I looked into the bulb lifespan thing. Luxim recommends replacement after 70% degradation while iunu recommends replacement at 3-4% degradation. This explains the massive difference in service life. Here's the catch, last time I checked you had to send you luxim fixture back to the manufacture to get a bulb replacement while iunu bulb replacement is DIY. Iunu's bulb is also supposed to have more red. Some would say that this means that iunu is just trying to get people to repurchase bulbs more often, others would say that you'd be crazy to let your bulb degrade to 70% when your growing a crop that sells for so much. I'd let my bulb degrade to 70%.... if I was growing lettuce.
 
Anyhoo it looks like strike 2 for the Vero unless Toshiba, (who make the COBs for Bridgelux) has made some deal to sell their tech with the new Bridgelux, aka China Electronics Company, it doesn't look good for those folks who've cut their heatsinks for 29s :(. Or at least the Vero we know and love today is going bye-bye.

Toshiba plans to exit packaged LED business as part of semiconductor business restructuring
http://www.ledsmagazine.com/article...-of-semiconductor-business-restructuring.html
​
"After spending significant money and resources on developing GaN-on-Si LED technology, Toshiba will evidently no longer pursue the white LED business and plans to shutter the organization by the end of this year...... Bridgelux has since been acquired by China Electronics Company (CEC) but had planned to continue its Toshiba relationship and even act as the primary distribution source of the Toshiba-manufactured GaN-on-Si packaged LEDs."

And from:
http://www.ledinside.com/news/2015/10/toshiba_kisses_goodbye_to_white_led_business
"After exiting from the white LED market, the company will be able to integrate resources and focus on power devices and controllers for LED chips, optic components for telecommunications and other market applications, where there are greater market growth potential."

http://www.svmi.com/taiwan-makers-may-benefit-from-toshiba-plans-to-quit-white-light-led-production/
Toshiba, as part of plans to reduce in-house production of LED epitaxial wafers and chips, will stop production of white-light LED chips and increase outsourcing, which is likely to bring in more orders for Taiwan-based LED chip makers, according to industry sources.
Toshiba stepped into LED production through transferring GaN-on-silicon technology from US-based Bridgelux in 2012, the sources said. In 2013, Toshiba planned to expand investment in LED production, but yield rates for LED chips based on GaN-on-silicon have been significantly lower than those using sapphire wafers, the sources indicated. Thus, costs for producing LED chips based on GaN-on-silicon are relatively high and this is possibly the reason Toshiba plans to stop producing white-light LED chips, the sources said.

...so are things a little hazy here or have I smoked too much? :eyesmoke: Probably some miscommunication obviously.

big difference between miscommunication and out right lying @oliggtower clones don't "break surface" anyways i remember another shotty journal somewhere with these lights presented in a similar matter. .. walking a fine line

This makes me sad. But @oliggtower brightened up my day lol (looks like his posts were pruned :blsmoke:)
 
Hey guys so im sure some of you LED growers will be happy to hear that im making the switch from HPS. I need some advice though. I have a tent that is 2'8"2'8"x5'3". Im looking for the cheapest LED possible and from the reading ive done anything from a 300w or 400w full spectrum light would work. Any recomendations or anything of the sort?

What's your budget? You want to look into a cob led light that uses cree cobs or bridgelux vero.

Cheapest? DIY with Veros. Most efficient as of date? CXB3590 cobs. For safety reasons I decided against a full-on DIY (not so confident with AC) and just bought Optic Lighting kits. There are a couple on the market that are similar/close to each other in price/performance - GoGreenLEDs, Pacific Lighting Concepts, A51, and couple of really new lights that are being tested by members here on RIU which will debut soon (keep your eyes peeled).

Better to start off with a budget. If you can spare ~$500-600 you'll be able to get some reliable and proven lights.
