Eight reference articles on the values that come back in every specification and every datasheet, from lumen and kelvin to service life, light pollution and obstruction lighting. Below them are the grant routes for the Netherlands and what we do when we guide an application.
We do not provide tax or subsidy advice. What we do do: explain how the schemes work, and provide the technical substantiation on which an application or notification is based. For clients, we guide the process from beginning to end.
Eight topics that come back in virtually every specification and every comparison. Not news blogs, but reference material that lasts: what the value means, how to read it and what to look for in a datasheet. All eight are online.
The values that determine whether the light on the field or terrain does what you want
Why a luminaire with more lumens does not automatically provide more light on the ground, and which number belongs in a specification.
What 3000, 4000, and 5700 K do in practice regarding vision, recognition, and the perception of the environment, and where amber 2200 K is appropriate.
What the Ra value measures, why cameras and sports federations set requirements for it, and why Ra alone is not the whole story.
The values by which you compare lifespan, warranty, and consumption with one another
How to read a service life specification: what the L and B values mean individually, and why a number without an LB code means nothing.
The difference between chip efficiency and system efficiency, why net lm/W is the only fair comparison, and how that affects the payback period.
What the two digits after IP mean, where the line is drawn between dustproof and waterproof, and why IK matters more than people think in sports and industry.
The topics where permits, neighbours, nature and aviation meet
The threshold values by zone, the regulations in ten European countries, and why "full cut-off" is the only implementation that boosts 0%.
Which light class belongs at which height, where the lights go on a crane and from when you must notify a crane or mast, country by country.
A lighting calculation says more than eight terms put together. We calculate your site or pitch free of charge, and an engineer replies within one working day.
That depends on one question: does your organization pay corporation tax. A subsidy is paid out and does not require that; a tax deduction reduces profit and therefore requires there to be profit. That is where the two Dutch routes diverge.
For amateur sports clubs, foundations, and municipalities: parties without corporate income tax. Subsidies are paid out, so you do not need taxable profit.
For BVs, NVs, and entrepreneurs with taxable profit. A tax deduction lowers the profit, so without profit there is nothing to cash in.
Regulations vary by country and often by region, and they change every year. That’s why we don’t list foreign percentages on our website,instead, we’ll work with you to explore them in detail.
Are you hesitating between the first two: on the EIA page is a table that shows per organizational form which arrangement is and is not possible. That is the fastest way to see if you are on the right page.
If JEL implements the project, we will guide the subsidy process from beginning to end. Not as a separate service, and not as a subsidy agency: we are about the lighting and the underlying figures. The application itself goes through you, your accountant, or your advisor.
We deliberately keep that distinction sharp. We can substantiate a lighting plan; whether your application is approved is determined by the agency.
Describe in two lines who you are and what you want to replace. We will tell you which arrangement applies to your situation, which documents are required for this and what we will supply. Reply within two working days, and no assignment is required in return.
