== Description ==

Sun lamps provide artificial light to roofed growing zones (greenhouses) at high power expense (2,900 watts). A sun lamp will illuminate tiles within a five-block radius at 100% and outside tiles at only 50% or less. Sun lamps automatically turn themselves off at night to save power while the plants are resting. Once installed, the lamp menu offers the option to create a growing zone that matches its radius.  Sun lamps become available after [[research]]ing Electricity.
  
Sun lamps are devices used to assist plants growth indoors by providing powerful enough light that can bright like sunlight, supporting [[hydroponics basin]]s to generate plantations where areas sunlight does not reach.
 
Sun lamps exposed to the open are vulnerable to weather, rain and snow, risking short circuit, fire explosion and damage to its surroundings. Sun lamps automatically turn themselves off at night when plants are resting.
 
  
A sun lamp uses over 30 times as much power as a [[standing lamp]] does, and therefore shouldn't be used to only light up a room, especially if it's a small room.

== Hydroponics ==
 
 
It is possible to fit 24 hydroponics basins inside the "brightly lit" area of a sun lamp with the following configuration:

This Setup will use 4580W at day and 1680W at night, a [[Solar generator]] produces 1700W and a [[Geothermal generator]] 3600W,
 
so 2-4 Solar Generators (and a few [[Battery]] ) or one Geothermal generator are needed to power it.
 
 
If there is a roof over the hydroponics area, it may be wise to use the four empty tiles for roof support columns.  This is not necessary if there are supports immediately outside the sun lamp's radius.
 
 
 
== How to prevent short circuits ==
 
If it is raining on the sunlamp it '''WILL''' short circuit and cause fires. To prevent this, simply build a wall and build some roofs connected to the wall over the sun lamp.

&#9673; - Sun lamp <br/>
 
&#9641; - ''[[Wall]]''<br/>
 
&#9634; - ''[[Power conduit]]'' <br/>
 
 
<pre>
 
Roof under construction.
 
Build walls first, then sell unnecessary walls and last build the lamp

</pre>
 
 
Please note that a recent change in how roofing is created has made it so that there is a hole in the middle. The fix is to place the lamp on a square the walls previously stood on.
 
 
<pre>
 
Roof done, the lamp is protected & the unnecessary walls has been sold. (the lamp is moved to be under the roof)

Sun lamps provide artificial light to roofed growing zones (greenhouses) at high power expense (2,900 watts). A sun lamp will illuminate tiles within a five-block radius at 100% and outside tiles at only 50% or less. Sun lamps automatically turn themselves off at night to save power while the plants are resting. Once installed, the lamp menu offers the option to create a growing zone that matches its radius. Sun lamps become available after researching Electricity.


Short circuits

Rain on a powered sun lamp will cause short circuits and fires. A roof will prevent this.

If the area is unroofed, you can simply switch the sun lamp off.

Greenhouses

Sun lamps allow indoor plantations but don't produce heat, so heaters may be required to attain proper conditions for plant growth. Solar flares will cut the energy power so prepare a shelf with emergency wood to build campfires to keep the room temperature above -10C. Double-width walls provide more insulation against temperature changes (and thus save power with heaters or coolers), as well as better protection from attacks.

Hydroponics basins increase the growing rate in low fertility tiles but are dependent on electricity, without power all plants on it will die soon.
