    Hi Friends

    I have 2 400W MH to put on my tank, When I bought them they came with Veture "designer blue" bulbs, not rated but recommended by Hennie, unfortunately 1 of the bulbs the outer shield has broken, so I need to replace it/them?

    What should I get? Thinking of BLV's but worried about the colour..... the 20 000K are quite cheap and I'm thinking they might burn with the colour equivilent to say 14-16 000K ? Is there anyone who runs 20 000K BLV that could advise?

    Thanks Jacques, but don't think it will give me a true reflection of the colour as its mixed 14 and 20K?

    Don't laugh Alan but its only 550mm, yes I know its an overkill, but got them for a song and it would cost alot more to convert to 250W?

    It works out to about 2W per litre
