One benefit to using gel instead of water is that you can stratgically layer the lights throughout the vase. With water you have to just have one in the bottom and one at the top. With the gel, it is kind of like making lasagna in a vase! See this link on my website for my "FloraLyte Lasagna Recipe"
Ok, its not really called that. But that is what it reminds me of.

It is hard to not get striping though... even with the gel. We sell the gel filler, if you are looking for it. The "marbles" are technically called Crystal Accents Water Holding Deco Beads and the "smushy" are called Crystal Accents Water Holding Gel Crystals. The Crystals are better for use in eiffels. Here is our gallery of pictures of the crystals with the floralytes...

Remember that with the light bases, there are three different types.
They all say "Super Bright" led lights. However, what you need to look at is the
QUANTITY of lights per base. There is a 4" with 9 lights, an 8" with 13 lights, then an 8" with 31 lights. We just decided to start carrying these (got them photographed and priced less than 8 hours ago!) But we chose to only carry the 8" 31 light ones because it seems that those "in the know" feel they are much superior. So when looking at light bases, be sure you are comparing apples and apples... an 8" with 31 lights will give off considerably more light than a 4" with 9 lights. However, my humble opinion, is that the 8" ones are kind of big for use with an eiffel, unless it is 24" or larger. But that is PURELY opinion. I am sure many people would say I don't know what I am talking about.
Also, with eiffels, there are clear glass, then painted white glass, then frosted glass. You might have a frosted glass. But if the picture was originally with the painted white glass instead of the frosted, you have a whole another animal.
Oh, and then there is the whole issue of monitor differences, and what cameras do to things. Who knows what the original design truly looked like! You might be doing everything right, it might just be technology messing with everything!
