Next-generation CSP solution - PoW (Phosphor-on-Wafer) LED package
Samsung’s Phosphor-on-Wafer (PoW) LED package technology embraces the advantages of CSP LED packaging, while overcoming limitations of cost reduction by upgrading the chip manufacturing process through the use of 8-inch GaN-on-Si wafers instead of 4-inch sapphire wafers. This transition will enable a higher quality CSP LED package by eliminating the chip rearrangement process. The reason for this is that the phosphors can be directly coated on the surface of the GaN-on-Si wafers before being diced, while sapphire wafers have to be cut into chips first and then rearranged to be coated with phosphor.

By simplifying the LED component manufacturing process and improving LED package quality, the PoW LED package technology is expected to contribute significantly to the growth of the LED lighting industry.

Samsung has already applied its PoW technology to 4-inch wafers in flash LED packages for mobile devices since several years ago. Samsung also plans to utilize the PoW technology for its new CSP product line-up for lighting applications by the end of this year.

Samsung will showcase the new CSP products and technologies at the Light + Building 2016 event under the theme “Lighting & Beyond” in Frankfurt, Germany, March 13th – 18th. Visit Booth B04, Hall6.2 to learn more about Samsung’s differentiated LED technologies and innovative component solutions.

COBs are ultimately just SMDs smashed together in a very tight package.
Waffle LEDs obviously have advantages over SMDs so they must also have those same advantages against COBs
 
Great little L+B wrap-up article from LED-Inside. Nichia CSP :). Yeah PSU, COBs are here to stay, :roll: Pfffffft. Maybe for the lazy DIY stoner, but for those who want more, NO WAY!

And for those who doubted Samsung's offerings methinks your math was a bit old :).

Its a street light re-purposed as a growlight. They claim the spectrum is special for growing, bullshit, look up the company that actually manufactures these. They may be good, but why bother bullshitting people?

Want to see some more BS handed out by growlight maker, black Dog?: Take a little science and twist it to sell your lights!

What do you guys think of this companies offerings for cloning/vegging?

right idea but a bit underpowered.

- 96 watts of leds will NOT replace a 4 tube t5ho.
- except for seedlings\clones the typical problem with T5HOs is the lack of density. ie it takes a full roof of T5HOs to productively flower.

from sol-solutions:
"The 4 strip fixture, at 96 watts, and the 8 strip fixture, at 192 watts, are viable alternates for 8 tube T-5 type fixtures (which run at 440 watts, need regular bulb replacement, and contain toxic mercury waste)."
 
Chip-On-Board (COB) or "Integrated" LEDs are created by placing many low-wattage (typically 0.5W or 1W) LED dies side-by-side on a circuit board. This allows companies to claim very high wattage LEDs, but for example the "50W LEDs" are just 50 1W LEDs side-by-side (or 100 0.5W LEDs). It isn't possible (yet) to make long-life COB LEDs with higher-wattage dies, as it isn't possible to remove the heat from the COB assembly quickly enough to prevent damage to the LEDs. For example, there are now some COB LEDs made with 3W dies on the market, but these are still only run at 1 watt per die and still have a tendency to burn themselves out within a couple months. COB LEDs also often lack primary lenses on the LEDs, which actually diminishes the light output from the LED.

Wow , blatant lies & mis-information & they have a Big Sale on right now so hurry on down
 
Hey guys new to led and been catching up on all the info. Been searching for the best , most efficient led out there and came across a light that I havent seen anywhere
http://www.leoledgrow.us/en/shop/fspectrum-c-led-125w.html
"
leoLED fSpectrum C provides an excellent density of photosynthetically active radiation (PPFD) onto the plant canopy. With an efficiency of 2.5 PPF/Watt, the fSpectrum C is the most efficient horticultural lighting system on the market. 4 fSpectrum C (500W power draw) outperfom a 1.000W High-Pressure Sodium Lamp (1.7 PPF/Watt) in terms of quality and yield. A far superior distribution of light on the canopy, less heat in the grow room as well as an effective pure-white output spectrum guarantee healthy plant development at maximum photosynthesis rates." Wondering whats your thoughts on this light?

it uses 3070s which are a generation behind the current 3590s used in commercial builds by forum members like tasty, johnson, plc, etc

other than that, nothing at all magical about it. any build using 3070s/3590s/vero 29s at the same current/wattage will perform similarly
