bulb question w/poll

[Michael7979]

I run 400 watt radiums on HQI ballasts but thinking of changing bulbs due to the cost of replacing the radiums every 7 months. So out of the 3 which would you choose?

Radiums... IME thay have the best overall color even though they are a little more then the others. You pay for quality

i voted for radiums as well.... "often imitated, never duplicated"

Have radiums now but I chose to go with Helios on my next purchase.... they have a higher par and heavier on the blue end..... I will be posting pics with comparison when they are put on my tank.... But for right now I have radiums and I do not have one problem with them..... just going to see what else is out there. Helios has higher par, stronger blue violet coloration and spikes higher at 450nm on a PFO HQI ballast per Sonjays site..... but as for experience I have only tried the radiums
