|SKU||Phoenix Metal Halide 14K Double End Bulb|
|Lighting Type||Metal Halide|
The best way to differentiate between a 150w and a 250w DE metal halide bulb is the form of the bulb itself. The ends of the 150 will have small ceramic cylinders on the ends like the bulb pictured on this page. https://www.bulkreefsupply.com/phoenix-metal-halide-14k-double-end-bulb.html
The socket for the bulb will have small metal pins that fit into the small indentations on the ends of the bulb.
A 250 watt bulb will have metal "blade" type endcaps that seat into slots in the fixtures sockets.
You can see this type of bulb on this page https://www.bulkreefsupply.com/hamilton-metal-halide-10k-double-end-bulb.html
I hope this helps!
The light when mounted higher will have a wider spread across the tank. This 1 foot of air will not hinder the light penetration too much however it does spread the light out further depending on the fixture itself. You of course can tell by seeing how the corals respond to the light or with the use of a PAR meter, but in many cases for deeper tanks (24"+) a larger wattage is required. Feel free to let us know if you have any further questions!
They are interchangeable depending on the ballast used. As long as the ballast can handle the correct wattage it will work well! Feel free to let us know if you have any further questions!
