How can I pay?
Payment Methods
Do you ship to my country?
Yes, we work with a international express courier for all shipments and can also ship our product to your country.
Most country destinations have been activated, so in the order process you can probably choose your own country. If your country does not appear on the list please contact our customer service.

We currently do not ship to the USA; due to the 110V USA power supply the units will not function correctly.
How safe are your products?
Our products have been developed and tested with great care, we advise you to follow the safety instructions:
-For the safety of everyone in your household, never remove product covering/case. Do not try to replace parts by yourself. Always consult a professional electrician.
-Reduce the risk of fire or electric shock; the LED should never be exposed to rain or moisture. Objects filled with liquids, such as vases, bottles, etc should not be placed on or near the LED.
-Never directly look in the light, this will damage your vision and can cause temporary blindness.
-Do not install near any heat sources such as heat emitting lights, radiators, electrical heaters, or other heat sources.
-Only use the original power cord and only use with approved accessories. If the provided plug does not fit into your outlet, consult an electrician for replacement.
-When plugging the power cord into the wall unit, make sure it is fully inserted in the socket.
-Protect the power cord from being walked on or pulled, particularly at plugs and the point where the power cord exits the LED grow light
-Use strong cables or chains to position the unit and make sure that they have been well fitted to the ceiling and the light. We are not responsible for drop-damage caused to the LED.
-Unplug the LED during lightning storms or when unused for long periods of time.
-Refer all servicing to qualified service personnel. Servicing is required when the LED has been damaged in any way, such as power-supply cord damage, liquid /objects have fallen into the LED, the LED unit has been exposed to rain or moisture, not operated normally, or has been dropped.
-For disposal or recycling information, please contact your local authorities, electronic devices should be recycled after their use.
What is your warranty protocol?
Each light in the Crazy LED collection has been carefully chosen for component quality and manufacturing quality. The guarantee we give varies from model to model.

How does it work?
The warranty covers the repair or replacement of your LED grow light in case of defects or malfunctions. The warranty period is valid from the purchase date. It includes all components and labour needed to get the device working correctly again. If a component is no longer available we will replace it with an equivalent component or exchange the LED grow light. The warranty period is valid from the purchase date. Crazy LED will not extend the warranty period in case of repairs or replacement within the warranty protocol.

Our warranty covers normal usage of your LED grow light in the country from where it was purchased. We can refuse shipments to areas other then where it was first purchased. In case of repairs the buyer has to pay the postage for shipment to our office and the items must be returned in its original packaging. We will do our utmost to solve any issues as quickly as possible. The warranty does not apply without the original purchase invoice.

The warranty does NOT cover:
Defects caused by: -Accidental damage. (such as dropping the unit, spilling water on it, etc) -Careless operation. -Any other use other than what the unit is intended for (indoor home growing) -Use of components and accessories provided by third parties. -Faulty assembly, installation, or repairs by others then Crazy LED. -Shipment damage of the LED grow light from the customer to our office due to poor packaging.

If you experience any problems with your LED grow light after the warranty period we still advise you to contact us. Perhaps there is an easy and effective way to help you solve the problem, even after the official warranty period ends
How long will shipping take?
Shipping times depend on your destination. At most European addresses your order will be delivered within 24 hours after receiving payment. Some remote areas and destinations outside of Europe will take longer.
Where do you produce your lights?
It varies from supplier to supplier. We have supplied indoor grow lights from Europe and North America.

About LED & Light

Our mission is to offer the most innovative and qualitative luminaires and bring the benefits from (horticultural) technological developments to your home. We stand for a specialized and scientific approach and through this, we offer reliable, distinctive and knowledge-based service to our customers.

To ensure the quality we offer, all luminaires are professionally tested before they are added to our collection. We are exclusively working with professional growers who are always testing the most innovative LED fixtures available. From our perspective, this is necessary as the market is flooded with (very) low quality products and the published specifications are often unreliable, incomplete or the measurements can't be compared. Consequently, misinformation is intentionally provided to consumers, which negatively affects the choise, growing experience and the result. Therefore we want to measure and publish the results ourselves; We want to know what we sell to our customers.

So we only select LED fixtures that have proven their quality. The reason why we sell a variety of luminaires (instead of one true LED ''champion'') is because there is more than one solution and more than one grower or method, every situation is different.

As a customer, we can imagine that it is a true challenge to evaluate light sources for horticultural lighting fixtures that meet your specific needs. We offer a knowledge-based service portal that serves as a (growing) guide and customer service for (indoor) horticulture. This is missing at the moment and the majority of the people are blinded by all the marketing and possibilities.
For a well-founded and thoughtful decision, you need to know some basics of LED and light. We will explain some terms (Lighting Metrics) you need to understand to substandiate your final decision.

In order to invest in the proper horticulture lighting system to meet your cultivation and business goals, you need to know the PPF, PPFD, and photon efficiency to make informed purchasing decisions. However, these three metrics should not be used as sole variables to base a purchasing decisions. There are several other variables such as form factor and coefficient of utilization (CU) that need to be considered as well.

All factors need to be used in combination to select the most appropriate systems based on your cultivation and business goals, and the take home message is that PPF, PPFD, and photon efficiency are the proper metrics used by scientists and industry leading horticulture lighting companies. If a company does not provide you with the correct metrics used for horticulture lighting, they should not be selling horticulture lighting systems, and you will not be able to verify the true efficacy of their system.

Your evaluation and final choice depend on many factors:
◽ your grow environment (for example: temperature, humidity, air circulation, background noise, heat etc.)
◽ the strain you are growing (strains react differently on different types of lighting, techniques etc.)
◽ your (personal) growing technique (are you using the ''SCROG'', ''SOG'' or an other method/technique ?)
◽ your personal health (for example: does your health allow you to work on your knees, to bend, to ''SCROG'' ?)
◽ your goal (are you growing seedlings, cuttings, mother plants; do the crops remain in the vegetative phase, or do they bloom as well ?)

There are multiple considerations that a consumer or business faces when evaluating light sources to use for horticultural lighting:
◽ PAR, PPF, PPFD measurements ?
◽ What is the photon efficiency ( μmol/J) ?
◽ Is the spectrum tuned for the application ? Is the spectrum adjustable or fixed?
◽ How is the uniformity of light distribution ?
◽ What is the fixture lifespan ? How many years of warranty ?
◽ What is the process for spare parts and repairs ?
◽ Does the fixture have adjustable power ?
◽ Which LED brand and diode is used? (Nichia (Japan), Osram (Germany), CREE (USA), Showa Denko (Japan), Philips (Netherlands), Toyoda Gosei (Japan), Citizen Electronics (Japan), Epistar (Taiwan), GeneLite + Genesis Photonics (Japan + Taiwan), Luxeon (Canada), Bridgelux (China), Epileds (China) etc.)
◽ Which LEDs are used, COB or normal ? Any special optics used?
◽ Can multiple fixtures be connected together ?
◽ What are the main benefits for the specific technology ? Any special features used ?
