Correct, two 22's will definitely get you better penetration with the additional bulb. Not to confuse you even more but, bulb selection can make a difference too though lol. The sunblaze comes with very blue heavy bulbs, not bad bulbs at all but last I looked them up not much info about them. For 6500k t5ho I prefer ge starcoats though ( F24W/T5/865/ECO for the 24" fixtures). They have crazy par numbers per the reefers despite lowish lumens and can be found insanely cheap online. However, before you buy two 22' let me read a bit more on the citizen cobs today/ tonight. From what I was seeing last night I think the 1818 is looking like a nice replacement. To put it in context, average output for a 2 ft 24w t5ho bulb is ~1750/ 2100 lumens, at 25w the 1818 cob is putting out double that and focusing it all generally speaking, down

I agree with everything posted with the exception of the "arcadia" fixtures. Mistking will remain off my radar but that is for personal reasons and nothing that would cause me to not recommend them beyond it. As to the "arcadia" fixtures, singles, be it lyr or places like reptile basics, are rebranded sunblaze/ sun blaster products from everything I've seen and know of the lights themselves. Great products and worth it just not at lyr pricing for it. Sunblaze carries a 5 yr warranty, sun blaster carries a 1 yr warranty, both made by Sunlight Supply inc which is now part of Hawthorne Gardening. Biggest differences beyond warranty between the sun blaze supreme 21 and the sun blaster are reflector style and end caps to prevent the light spill the sun blaster suffers from on the supreme. The dual and quad tube fixtures as has been mentioned in the fb groups are rebranded odyssea fixtures that are not efficient at transferring light with the single reflector for all tubes. Todd has even posted the proof himself as to why those fixtures aren't worth the money for them on top of horribly short warranty period.
Coming from planted tanks, I've seen threads with issues from those fixtures that surprisingly isn't really mentioned in this hobby much. Early versions catching on fire, ballasts and timers going out to quickly... Sadly with the short warranty you're left buying more parts to fix it or scraping it and going with a better fixture afterwards. With as expensive as this hobby already is it just doesn't make sense to me to cheap out on the fixture when a better one can be had, in some cases for less, then the odyssea depending on where you get it. I do love the arcadia uvb bulbs though and whole heartedly agree with you on using them.
