so this was in some sticky about lighting, someone mentioned it but nobody really talked aboot it, so anyone have experience with these?
[FONT=Verdana,Arial,Helvetica,Sans Serif][SIZE=+1]Control the shape and growth of your plants with light - Photoponics. [/SIZE][/FONT]Introducing Nlite - a range of Quality Fluorescent lamps designed for PLANTS (also perfect for aquaria and reptiles).
Each lamp has choice of 3 colours :- Blue and Red and PURple.
[SIZE=+1]PURple ? YES. Introducing the Nlite PURple[/SIZE]
[SIZE=+1]PUR stands for Photosynthetically Useful Radiation.[/SIZE]
Humans are most sensitive to green light (green curve below). Wide spectrum light with lots of green appears to us as white.
Plants use a part of the sun's spectral range to grow. This is known as the PLANT ACTION SPECTRUM. (yellow curve)
Light energy in this range is measured as PAR - Photosynthetically Active Radiation.
Plants look green because they reflect most green light, and absorb most red and blue.
Plants therefore respond more to light from the RED and BLUE ends of the plant action spectrum.
PURple lamps have this ideal spectrum shaped the way plants "see" the light. (white curve) ( a little spike of green is left to allow US to see plants lit by PURple)
[SIZE=+1]PUR is the amount of the PAR that the plants use efficiently. [/SIZE]
Nlite lamps are made in 3 PUR colours. Plants change their growth response to different levels of these PUR colours :-
(By contrast HPS lamps give out 100% PAR, but only 33% PUR ! mostly they give out green and yellow and harmful infra red)
We recommend greater than 50 watts of Nliteper 30cm x 30cm (square foot) of horizontal canopy. Light distance can be as little as 3cm, the closer the better.
All Nlites are T5HO ! Thats 48% more light than standard T5.
Nlite Fluorescents have these Features and Benefits:-
What is Lumen output of these lamps ?
Though given, it is irrelevent ! Lumens are for Humans not plants ! Lumens measure how we see light. Our eyes prefer green light. Green light has the most Lumens, Red and Blue the least. Most fluorescent lamps are made to look bright for humans by adding huge spikes of greeny yellow light.
Lumens only measure how BRIGHT the light appears to us.
Lumens cannot measure light useful to plants - PUR
*What is the Kelvin colour temperature of these lamps ?
The Red and Blue lamps DO have a Kelvin colour specification, but the PURple does not.
The Kelvin color simply describes to which temperature a block of Carbon must be heated in order to match the apparent colour of the lamp.
It does not measure the Quantity OR Quality of the light for growing plants.
PURple does not appear in the Kelvin scale as it is a mix of TWO colours.
What is the CRI ?
CRI allows comparison between different lamps ability to render color, It measures how much the Red and Green and Blue reflected light, looks RIGHT to our eyes.
It does not measure the Quantity or Quality of light useful to plants - PUR

Nlite lamps are made in 3 PUR colours. Plants change their growth response to different levels of these PUR colours :-
- PURple - The Ultimate 100% PUR. Purple is perfect for all stages of plant growth, germination, root development, tuber and bulb formation and gives lots of internodal growth, and budsites. Great for orchids, cacti, ethnobotanicals, coral, sea plants etc. A small amount of NEAR UV ensures good production of essential oils - Great for Basil and other aromatic herbs.
- BLUE. stimulates chlorophyll production more than any other colour, encouraging thick leaves, strong stems and compact vegatitive and leafy growth, keeps internodes close. Great for seedlings and cuttings. Perfect for plants cropped before flowering stage, such as lettuce and cress. With only blue light your plants stay short, and maturity takes much longer
- RED encouages maturation of fruit and flowers towards the end of growth cycle. Use exclusively for the finishing period to maximise your fruit or flower yields. Perfect for flowers, peppers, and tomatoes. Too much red and no blue early on will S...t......r....e.......t.....c....h... your plants and increase internode distance.

Nlite Fluorescents have these Features and Benefits:-
- Low Power Operation , thus saving costs and earth resources
- Low working temperature allowing more light closer to your plants because of massive heat reduction.
- 200W professional versions use separate ballasts to massively increase control over infra-red radiation (damages all plants), heat build-up, safety and humidity problems.
- Seperate ballasts reduce future Economical and Environmental costs, only replacement lamps are needed. This significanly reduces replacement costs in subsequent grow cycles.
- Separate ballasts increase light output, reduce electricity use. and run silently
- Plastic shell is made of recycled material.
- Reliable.
- 6 MONTH GUARANTEE against manufacturing defects.
- Best Quality well engineered PLANT fluorescent lamps.
- Compatible with ordinary E40 screw lighting fixture.
