Key Features Skyline 400 MK2

1. Advanced Aluminium-Fin heatsink, providing cooling without needing noisy fault prone fans.

2.White – Light.

Our full spectrum blend appears visually primarily white due to the balance of the output spectrum,

which both the plants and growers both LOVE.

3. The modular structure is industrial grade and highly serviceable and upgradeable.

4. Heavy-duty KIT.

5. Unique design using a removable power supply and light source

6. Supplied with a generous 5M cable and mains plug.

7. Weight 6.5KG

8. Only using 200w power


Very quickly rising to the top of our hot list, the full spectrum Skyline led grow lights is a massive performer.

The combination of stealth-bomber looks and large surface area of powerful LED point sources set the scene and follow up with explosive results in the growing phase, huge flowering and unbelievable yields of rock solid sticky buds.

With the high yielding varieties or anything for that matter, this lamp can really drive them beyond expectation.

Real-world results are important to us, and this full spectrum Skyline led grow lights definitely is a massive move in the right direction.  But of course, we’ve also put the final setup through the usual barrage of tests to characterise its performance and give you the figures you’ll want to know.

Photosynthetic Photon Flux -PPF

The unit used to express PPF is micromoles per second (μmol/s).

This is probably the second most important way of measuring a horticulture lighting system but, for whatever reason, most lighting companies don’t list this metric.

Most importantly to note that PPF does not tell you how much of the measured light actually lands on the plants, but is an important metric if you want to calculate how efficient a lighting system is at creating PAR.

Photosynthetic Photon Flux Density-PPFD

PPFD is photosynthetic photon flux density measures the amount of PAR that actually arrives at the plant, or as a scientist might say: the number of photosynthetically active photons that fall on a given surface each second”.

PPFD is a ‘spot’ measurement of a specific location on your plant canopy and it is measured in micromoles per square meter per second (μmol/m2/s).

If you want to find out the true light intensity of a lamp over a designated growing area (e.g. 4’ x 4’), it is important that the average of several PPFD measurements at a defined height are taken.

Lighting companies that only publish the PPFD at the centre point of a coverage area grossly overestimate the true light intensity of a fixture.

A single measurement does not tell you much, since horticulture lights are generally brightest in the centre, with light levels decreasing as measurements are taken towards the edges of the coverage area. (Caveat Emptor: Lighting manufacturers can easily manipulate PPFD data.

To ensure you are getting actual PPFD values over a defined growing area, the following needs to be published by the manufacturer: measurement distance from a light source (vertical and horizontal), number of measurements included in the average, and the min/max ratio).

  1. Andy

    Bad ass led.
    It’s more a case of love, No fans and silent.
    Had grow northern led before and it worked ok, but was loud and made your
    house look like a brothel.

  2. Old Dog

    I am growing over 24 years and always use sodium and metalhelid to grow lovely big buds.
    every summer I stop growing for 3 months but this year my friend got me into led from
    and this lights fucking works. managed with the heat ok and buds was big and solid.
    I am going try this led in winter to see how they do.

  3. David

    Just finished my first grow with skyline 400 I got amazing result more than twice the yeild of my previous led and no noisey fans I would highly recommend this light it is in class of it’s own as you can imagine I am a very happy customer thanks muddy for an amazing light more people need to know about skyline LEDs !

    For a while i been looking at changing to led lights but neve4 had the courage to take the plunge. Thanks to a good mate i found Muddys website and very soon got my first led light soon followed by a second and then a third. So far the results are rely good and my environment is now a lot cooler and less humid. Muddy was always really helpful in the process and i would recommend his products and service to anyone who’s looking to upgrade their lighting system.
