What kind of lights are these?

My friend let me borrow these lights he found.
I know they are a 250 wattage.
I have a hps sunburst ballast with a 250 w hps light in now.
Would i be able to use this bulb in it?

Do you have a pic?

i meant to put the pics up i dont know what happened
Here they are..

maybe metal halide?

There should be some type of stamping on the base of the bulb that will tell you exactly what it is. Look closely all around the base. All of the manufacturer's stamp there bulbs......

Clean - Ace .99H
R (EYE)
MT250DL CE
Japan

Here ya go....it is a metal halide...

Hortilux Clean Ace - 250 Watt Metal Halide Bulb - Universal - MT250DL



should NOT be used with a HPS ballast. Either need a selectable ballast that can go both ways or a MH ballast.

dont use mh bulbs in your hps ballast, get a converter or universal ballast for mh and hps, i would recommend using cfl's for vegging and keep your hps for flowering, those mh bulbs can be dangerous.

Thank you kind sir that was very helpful
