This GB is for 250 DE's....................if anybody wants anything other then that, PM me .....................lets keep the thread about the 250's.....
cthetoy... Radiums are probably the brighest 250 watt 20k bulb out there. They will beat any other bulb in terms of par and color, that's why the price is typically higher, that and because its imported from Germany.
Anybody have some pics of the 250w Radiums with a HQI ballast?
I'm looking to switch my 250w DE Phoenix bulbs to Radiums but would have to change out 3 reflectors as well.
Also, what reflectors are you guys using for these? I was debating between the lumen bright and lumenarc mini for 180g tank with a 12" high canopy.
