50W grow light – full spectrum
If you would like to start growing veggies, herbs etc. indoor you will find the most expensive part of your setup will be the grow lights. Especially if you want to use LED grow lights to save on the power costs. Growing indoors is a lot of fun and can be done through summer and winter.
This 50w grow light will cost you about 20% of commercial grow lights, when we measure this 50W we get around 48 – 53 Watts!
These babies get real hot and a proper heatsink needs to be used. NOT USING A BIG ENOUGH HEATSINK WILL EITHER DAMAGE THE LED PERMANENTLY OR LOWER ITS LIFE EXPECTANCY AND PERFORMANCE.
STARTING THESE LEDS WITHOUT A HEATSINK FOR A COUPLE OF SECONDS WILL DESTROY THEM.
We sell a complete kit with heatsink and fan here if you prefer to buy the right stuff rather than build a heatsink with fan: 50W grow light full spectrum DIY Kit
How much light do you need? This is a very difficult question as different plants need different light requirements, some indoor plants are happy with just the natural lights you normally use in your house. With microgreens (edible sprouts) you will not need a lot of LED light either, about 50W per 0.5 square meters (even then I will put the lights higher, further away from the plant, than for veggie plants) – that’s about 2 big trays of microgreens!
When you deal with plants that flower and produce veggies and so on you will find they need much more light if you ever want them to bloom and produce. A 50W grow light full spectrum LED like these, about15 cm from your herbs will cover an area of plants roughly 300mm by 300mm. For one square meter, I would suggest 2 minimum and 3 ideally. But you will need to experiment a bit to get optimum harvests, that is part of the fun!
Building your own little herb garden indoors with the correct lightning does not just protect your plants from weather and bugs but also allow you to grow your favourites even through winter.

These lights are dimmable! Now that makes a huge difference for indoor growers! Seedlings need less light than plants that are bigger and in the growing state. Plants that bloom and producing the veggies even need more light. A simple dimmer like these ones on our site works perfectly and can be easily connected to 20 of these lights with no stress on the dimmer at all.
Lens with reflector
