Metal halide double ended?

[Easy7]

Been looking as I do from time to time to see what is around for gear. Last I checked up on MH DE bulbs what I read didn't sound good. Checked out growers house and saw new MH DE bulbs. Have you used these or others for veg? What do you know or understand about these bulbs and which brand of fixture. I like the idea of having blue for veg cycles. Plants just stretch too much without the blue. No problems here with DE HPS for flower.

This should of been in the grow room lighting sub forum, sorry.

I know there is a thread or two on the two 'older' brands. It's just that Gavita warns about their lights not being designed for mh. Something about start up timing/delay. At least some of de mh have jackets.
